2 Samuel 10:5

The city of Jericho had not been officially rebuilt (see 1 Kings 16:34). However, the site lay next to the largest and most reliable spring in the land, so people continued to live nearby.

Anyone traveling from Ammon to Jerusalem would pass by this area. Because of this, Jericho provided a quiet and private place where the men could stay hidden while they recovered from their humiliation.

The king of Ammon insulted David’s ambassadors, which led to two battles between Israel and Ammon (2 Samuel 10:6–12:31).

After the break in 2 Samuel 9, the story goes back to David's military successes. The Ammonites were likely the dominant political power in Transjordan (the area east of the Jordan) during Saul’s reign and the early years of David’s reign.

Tarry at Jericho--or in the neighborhood, after crossing the fords of the Jordan.

Here is, I. The great respect David paid to his neighbour, the king of the Ammonites, Sa2 10:1, Sa2 10:2. 1. The inducement to it was some kindness he had formerly received from Nahash the deceased king. He showed kindness to me, says David (Sa2 10:2), and therefore (having lately had satisfaction in showing kindness to Mephibosheth for his father's sake) he resolves to show kindness to his son, and to keep up a friendly correspondence with him. Thus the pleasure of doing one kind and generous action should excite us to another. Nahash had been an enemy to Israel, a cruel enemy (Sa1 11:2), and yet had shown kindness to David, perhaps only in contradiction to Saul, who was unkind to him: however, if David receives kindness, he is not nice in examining the grounds and principles of it, but resolves gratefully to return it. If a Pharisee give alms in pride, though God will not reward him, yet he that receives the alms ought to return thanks for it. God knows the heart, but we do not. 2. The particular instance of respect was sending an embassy to condole with him on his father's death, as is common among princes in alliance with each other: David sent to comfort him. Note, It is a comfort to children, when their parents are dead, to find that their parents' friends are theirs, and that they intend to keep up an acquaintance with them. It is a comfort to mourners to find that there are those who mourn with them, are sensible of their loss and share with them in it. It is a comfort to those who are honouring the memory of their deceased relations to find there are others who likewise honour it and who had a value for those whom they valued.
II. The great affront which Hanun the king of the Ammonites put upon David in his ambassadors. 1. He hearkened to the spiteful suggestions of his princes, who insinuated that David's ambassadors, under pretence of being comforters, were sent as spies, Sa2 10:3. False men are ready to think others as false as themselves; and those that bear ill-will to their neighbours are resolved not to believe that their neighbours bear any good-will to them. They would not thus have imagined that David dissembled but that they were conscious to themselves that they could have dissembled, to serve a turn. Unfounded suspicion argues a wicked mind. Bishop Patrick's note on this is that "there is nothing so well meant but it may be ill interpreted, and is wont to be so by men who love nobody but themselves." Men of the greatest honour and virtue must not think it strange if they be thus misrepresented. Charity thinketh no evil. 2. Entertaining this vile suggestion, he basely abused David's ambassadors, like a man of a sordid villainous spirit, that was fitter to rake a kennel than to wear a crown. If he had any reason to suspect that David's messengers came on a bad design, he would have done prudently enough to be upon the reserve with them, and to dismiss them as soon as he could; but it is plain he only sought an occasion to put the utmost disgrace he could upon them, out of an antipathy to their king and their country. They were themselves men of honour, and much more so as they represented the prince that sent them; they and their reputation were under the special protection of the law of nations; they put a confidence in the Ammonites, and came among them unarmed; yet Hanun used them like rogues and vagabonds, and worse, shaved off the one half of their beards, and cut off their garments in the midst, to expose them to the contempt and ridicule of his servants, that they might make sport with them and that these men might seem vile.
III. David's tender concern for his servants that were thus abused. He sent to meet them, and to let them know how much he interested himself in their quarrel and how soon he would avenge it, and directed them to stay at Jericho, a private place, where they would not have occasion to come into company, till that half of their beards which was shaved off had grown to such a length that the other half might be decently cut to it, Sa2 10:5. The Jews wore their beards long, reckoning it an honour to appear aged and grave; and therefore it was not fit that persons of their rank and figure should appear at court unlike their neighbours. Change of raiment, it is likely, they had with them, to put on, instead of that which was cut off; but the loss of their beards would not be so soon repaired; yet in time these would grow again, and all would be well. Let us learn not to lay too much to heart unjust reproaches; after awhile they will wear off of themselves, and turn only to the shame of their authors, while the injured reputation in a little time grows again, as these beards did. God will bring forth thy righteousness as the light, therefore wait patiently for him, Psa 37:6, Psa 37:7.
Some have thought that David, in the indignity he received from the king of Ammon, was but well enough served for courting and complimenting that pagan prince, whom he knew to be an inveterate enemy to Israel, and might now remember how, when he would have put out the right eyes of the men of Jabesh-Gilead, he designed that, as he did this, for a reproach upon all Israel, 1 Sam. Psa 11:2. What better usage could he expect from such a spiteful family and people? Why should he covet the friendship of a people whom Israel must have so little to do with as that an Ammonite might not enter into the congregation of the Lord, even to the tenth generation? Deu 23:3.

Tarry at Jericho - This city had not been rebuilt since the time of Joshua; but there were, no doubt, many cottages still remaining, and larger dwellings also, but the walls had not been repaired. As it must have been comparatively a private place, it was proper for these men to tarry in, as they would not be exposed to public notice.

When they told it unto David,.... Not the ambassadors, for they were not yet arrived, but some of their servants, perhaps, they sent before them to acquaint David of the usage they had met with:

he sent to meet them: he sent men to meet them with proper garments to put on, and to assure them how much he resented the indignity done to them and him, and would avenge it in due and proper time, and to direct them where to go for the present, as follows:

because the men were greatly ashamed: to proceed on their journey, and come to court in the condition they were:

and the king said; gave orders by the messengers he sent to them:

tarry at Jericho until your beards be grown, or "bud" (t):

and then return; that is, to Jerusalem; Jericho, though not yet built, might have some cottages at or near the spot on which it had stood, for the convenience of shepherds, and gatherers of fruit, in the plains of it; here the ambassadors were directed to go, it being the first place they came to when they had passed over Jordan, from the country of Ammon; and being a place where there were scarcely any inhabitants, or very few, was very proper for them in their present circumstances; and this confirms what is before observed, that it was now the custom of the Israelites not to shave their whole beards; or otherwise it was but shaving off the other half, and being now provided with other clothes, they would have had no need to have stayed at Jericho, but might have proceeded on in their journey.

(t) "germinet", Pagninus, Montanus.

He sent to meet them; he sent them clothes and other necessaries.

Tarry at Jericho; both because this was one of the first places which they came to in Canaan; and because it was now a very obscure village, and therefore fittest for them in their circumstances; for it was not built as a city till after this time, .

Until your beards be grown; for the want or loss of beards was esteemed a reproach among the Israelites.

This war, the occasion and early success of which are described in the present chapter and the parallel passage in 1 Chron 19, was the fiercest struggle, and, so far as the Israelitish kingdom of God was concerned, the most dangerous, that it ever had to sustain during the reign of David. The amount of distress which fell upon Israel in consequence of this war, and still more because the first successful battles with the Syrians of the south were no sooner over than the Edomites invaded the land, and went about plundering and devastating, in the hope of destroying the people of God, is shown very clearly in the two psalms which date from this period (the 44th and 60th), in which a pious Korahite and David himself pour out their lamentations before the Lord on account of the distress of their nation, and pray for His assistance; and not less clearly in Ps 68, in which David foretels the victory of the God of Israel over all the hostile powers of the world.
Sa2 10:1-2
Occasion of the war with the Ammonites. - Sa2 10:1. On the expression "it came to pass after this," see the remarks on Sa2 8:1. When Nahash, the king of the Ammonites, died, and Hanun his son reigned in his stead, David thought that he would show him the same kindness that Nahash had formerly shown to him. We are not told in what the love shown to David by Nahash consisted. He had most likely rendered him some assistance during the time of his flight from Saul. Nahash was no doubt the king of the Ammonites mentioned in Sa1 11:1, whom Saul had smitten at Jabesh. David therefore sent an embassy to Hanun, "to comfort him for his father," i.e., to show his sympathy with him on the occasion of his father's death, and at the same time to congratulate him upon his ascent of the throne.
Sa2 10:3
On the arrival of David's ambassadors, however, the chiefs of the Ammonites said to Hanun their lord, "Doth David indeed honour thy father in thine eyes (i.e., dost thou really suppose that David intends to do honour to thy father), because he has sent comforters to thee? Has David not sent his servants to thee with the intention of exploring and spying out the town, and (then) destroying it?" The first question is introduced with ה, because a negative answer is expected; the second with הלוא, because it requires an affirmative reply. העיר is the capital Rabbah, a strongly fortified city (see at Sa2 11:1). The suspicion expressed by the chiefs was founded upon national hatred and enmity, which had probably been increased by David's treatment of Moab, as the subjugation and severe punishment of the Moabites (Sa2 8:2) had certainly taken place a short time before. King Hanun therefore gave credence to the suspicions expressed as to David's honourable intentions, and had his ambassadors treated in the most insulting manner.
Sa2 10:4
He had the half of their beard shaved off, and their clothes cut off up to the seat, and in this state he sent them away. "The half of the beard," i.e., the beard on one side. With the value universally set upon the beard by the Hebrews and other oriental nations, as being a man's greatest ornament,
(Note: "Cutting off a persons' beard is regarded by the Arabs as an indignity quite equal to flogging and branding among ourselves. Many would rather die than have their beard shaved off" (Arvieux, Sitten der Beduinen-araber). Niebuhr relates a similar occurrence as having taken place in modern times. In the years 1764, a pretender to the Persian throne, named Kerim Khan, sent ambassadors to Mir Mahenna, the prince of Bendervigk, on the Persian Gulf, to demand tribute from him; but he in return cut off the ambassadors' beards. Kerim Khan was so enraged at this, that he went the next year with a large army to make war upon this prince, and took the city, and almost the whole of his territory, to avenge the insult.)
the cutting off of one-half of it was the greatest insult that could have been offered to the ambassadors, and through them to David their king. The insult was still further increased by cutting off the long dress which covered the body; so that as the ancient Israelites wore no trousers, the lower half of the body was quite exposed. מדויהם .deso, from מדוּ or מדוה, the long robe reaching down to the feet, from the root מדה = מדד, to stretch, spread out, or measure.
Sa2 10:5
When David received information of the insults that had been heaped upon his ambassadors, he sent messengers to meet them, and direct them to remain in Jericho until their beard had grown again, that he might not have to set his eyes upon the insult they had received.
