1 Samuel 6:13

People usually harvested wheat in May or June (late spring or early summer).

the lords of the Philistines went after them--to give their tribute of homage, to prevent imposture, and to obtain the most reliable evidence of the truth. The result of this journey tended to their own deeper humiliation, and the greater illustration of God's glory.

We are here told,
I. How the Philistines dismissed the ark, Sa1 6:10, Sa1 6:11. They were made as glad to part with it as ever they had been to take it. As God had fetched Israel out of the house of bondage, so now he fetched the ark out of its captivity, in such a manner as that Egypt was glad when they departed, Psa 105:38. 1. They received no money or price for the ransom of it, as they hoped to do, even beyond a king's ransom. Thus it is prophesied of Cyrus (Isa 45:13), He shall let go my captives, not for price nor reward. Nay, 2. They gave jewels of gold, as the Egyptians did to the Israelites, to be rid of it. Thus the ark that was carried into the land of the Philistines, a trophy of their victory, carried back with it trophies of its own, and lasting monuments of the disgrace of the Philistines. Note, God will be no loser in his glory, at last, by the successes of the church's enemies against his ark, but will get himself honour from those that seek to do dishonour to him.
II. How the kine brought it to the land of Israel, Sa1 6:12. They took the straight way to Beth-shemesh, the next city of the land of Israel, and a priests' city, and turned not aside. This was a wonderful instance of the power of God over the brute-creatures, and, all things considered, no less than a miracle, that cattle unaccustomed to the yoke should draw so even, so orderly, and still go forward, - that, without any driver, they should go from home, to which all tame creatures have a natural inclination, and from their own calves, to which they had a natural affection, - that, without any director, they should go the straight road to Beth-shemesh, a city eight or ten miles off, never miss the way, never turn aside into the fields to feed themselves, nor turn back home to feed their calves. They went on lowing for their young ones, by which it appeared that they had not forgotten them, but that nature was sensible of the grievance of going from them; the power of the God of nature therefore appeared so much the greater, in overruling one of the strongest instincts of nature. These two kine, says Dr. Lightfoot, knew their owner, their great owner (Isa 1:3), whom Hophni and Phinehas knew not, to which I may add they brought home the ark to shame the stupidity of Israel, that made no attempt to fetch it home. God's providence is conversant about the motions even of brute-creatures, and serves its own purposes by them. The lords of the Philistines, with a suitable retinue no doubt, went after them, wondering at the power of the God of Israel; and thus those who thought to triumph over the ark were made to go like menial servants after it.
III. How it was welcomed to the land of Israel: The men of Beth-shemesh were reaping their wheat-harvest, Sa1 6:13. They were going on with their worldly business, and were in no care about the ark, made no enquiries what had become of it; if they had, it is likely they might have had private intelligence beforehand of its coming, and might have gone to meet it, and conduct it into their own border. But they were as careless as the people that ceiled their own houses and let God's house lie waste. Note, God will in his own time effect the deliverance of his church, not only though it be fought against by its enemies, but though it be neglected by its friends. Some observe that the returning ark found the men of Beth-shemesh, not idling or sporting in the streets of the city, but busy, reaping their corn in their fields, and well employed. Thus the tidings of the birth of Christ were brought to the shepherds when they were keeping their flock by night. The devil visits idle men with his temptations. God visits industrious men with his favours. The same invisible hand that directed the kine to the land of Israel brought them into the field of Joshua, and in that field they stood, some think for the owner's sake, on whom, being a very good man, they suppose God designed to put this honour. I rather think it was for the sake of the great stone in that field, which was convenient to put the ark upon, and which is spoken of, v. 14, 15, 18. Now, 1. When the reapers saw the ark, they rejoiced (v. 13); their joy for that was greater than the joy of harvest, and therefore they left their work to bid it welcome. When the Lord turned again the captivity of his ark they were like men that dream; then was their mouth filled with laughter, Psa 126:1, Psa 126:2. Though they had not zeal and courage enough to attempt the rescue or ransom of it, yet, when it did come, they bade it heartily welcome. Note, The return of the ark, and the revival of holy ordinances, after days of restraint and trouble, cannot but be matter of great joy to every faithful Israelite. 3. They offered up the kine for a burnt-offering, to the honour of God, and made use of the wood of the cart for fuel, Sa1 6:14. Probably the Philistines intended these, when they sent them, to be a part of their trespass-offering, to make atonement, Sa1 6:3, Sa1 6:7. However, the men of Beth-shemesh looked upon it as proper to make this use of them, because it was by no means fit that ever they should be put to any other use; never shall that cart carry any common thing that has once carried that sacred symbol of the divine presence: and the kine had been under such an immediate guidance of heaven that God had, as it were, already laid claim to them; they were servants to him, and therefore must be sacrifices to him, and no doubt were accepted, though females, whereas, in strictness, every burnt-offering was to be a male. 3. They deposited the ark, with a chest of jewels that the Philistines presented, upon the great stone in the open field, a cold lodging for the ark of the Lord and a very mean one; yet better so than in Dagon's temple, or in the hands of the Philistines. It is desirable to see the ark in its habitation in all the circumstances of solemnity and splendour; but better have it upon a great stone, and in the fields of the wood, than be without it. The intrinsic grandeur of instituted ordinances ought not to be diminished in our eyes by the meanness and poverty of the place where they are administered. As the burning of the cart and cows that brought home the ark might be construed to signify their hopes that it should never be carried away again out of the land of Israel, so the setting of it upon a great stone might signify their hopes that it should be established again upon a firm foundation. The church is built upon a rock. 4. They offered the sacrifices of thanksgiving to God, some think upon the great stone, more probably upon an altar of earth made for the purpose, Sa1 6:15. And, the case being extraordinary, the law for offering at the altar in the court of the tabernacle was dispensed with, and the more easily because Shiloh was now dismantled; God himself had forsaken it, and the ark, which was its chief glory, they had with them here. Beth-shemesh, though it lay within the lot of the tribe of Dan, yet belonged to Judah, so that this accidental bringing of the ark hither was an indication of its designed settlement there, in process of time; for, when God refused the tabernacle of Joseph, he chose the tribe of Judah, Psa 78:67, Psa 78:68. It was one of those cities which were assigned out of the lot of Judah to the sons of Aaron, Jos 21:16. Whither should the ark go but to a priests' city? And it was well they had those of that sacred order ready (for though they are here called Levites, Sa1 6:15, yet it should seem they were priests) both to take down the ark and to offer the sacrifices. 5. The lords of the Philistines returned to Ekron, much affected, we may suppose, with what they had seen of the glory of God and the zeal of the Israelites, and yet not reclaimed from the worship of Dagon; for how seldom has a nation changed its gods, though they were no gods! Jer 2:11. Though they cannot but think the God of Israel glorious in holiness and fearful in praises, yet they are resolved they will think Baal-zebub, the god of Ekron, at least as good as he, and to him they will cleave because he is theirs. 6. Notice is taken of the continuance of the great stone in the same place; there it is unto this day (Sa1 6:18), because it remained a lasting memorial of this great event, and served to support the traditional history by which it was transmitted to posterity. The fathers would say to the children, "This is the stone upon which the ark of God was set when it came out of the Philistines' hands, a thing never to be forgotten."

Lowing as they went - Calling for their calves.
To the right hand or to the left - Some think they were placed where two roads met; one going to Ekron, the other to Beth-shemesh. It is possible that they were put in such circumstances as these for the greater certainty of the affair: to have turned from their own homes, from their calves and known pasture, and to have taken the road to a strange country, must argue supernatural influence.
The lords of the Philistines went after - They were so jealous in this business that they would trust no eyes but their own. All this was wisely ordered, that there might be the fullest conviction of the being and interposition of God.

And they of Bethshemesh were reaping their wheat harvest in the valley,.... Which began at Pentecost, in the month Sivan, about our May; so that there were many people in the fields, who were eyewitnesses of this wonderful event:

and they lifted up their eyes, and saw the ark, and rejoiced to see it; for though the ark while in the tabernacle was only seen by the high priest, when he went into the holy of holies; yet this having been brought out from thence, and exposed in the camp of Israel, some of this place very probably were there at that time, and had seen it, and knew it again by its form and splendour; and which gave them great pleasure to behold, which had been taken, and had been so long in the hand of the enemy, and the people of Israel deprived of it; which was the symbol of the divine Presence among them, and now restored to them again; and in this wonderful way, without seeking for it, without going to war on account of it, without paying a ransom for it; and was brought to them in a cart drawn by cattle without a driver, the lords of the Philistines with a large retinue following it. This is to be understood not of their looking "into" it, as they afterwards did, and were punished, as Kimchi; but of their looking "on" it.

The inhabitants of Bethshemesh were busy with the wheat-harvest in the valley (in front of the town), when they unexpectedly saw the ark of the covenant coming, and rejoiced to see it. The cart had arrived at the field of Joshua, a Bethshemeshite, and there it stood still before a large stone. And they (the inhabitants of Bethshemesh) chopped up the wood of the cart, and offered the cows to the Lord as a burnt-offering. In the meantime the Levites had taken off the ark, with the chest of golden presents, and placed it upon the large stone; and the people of Bethshemesh offered burnt-offerings and slain-offerings that day to the Lord. The princes of the Philistines stood looking at this, and then returned the same day to Ekron. That the Bethshemeshites, and not the Philistines, are the subject to ויבקּעוּ, is evident from the correct interpretation of the clauses; viz., from the fact that in Sa1 6:14 the words from והעגלה to גּדולה אבן are circumstantial clauses introduced into the main clause, and that ויבקּעוּ is attached to לראות ויּשׂמחוּ, and carries on the principal clause.
