1 Chronicles 27:8

David organized his reserve army into twelve divisions. Each division served for one month each year. Their duties likely included protecting borders, policing, maintaining order in conquered areas, manning fortresses, and taking care of military equipment like horses and chariots. The divisions were not based on Israel’s tribal structure. Each division included people from different tribes, showing the kingdom's integration.

Asahel--This officer having been slain at the very beginning of David's reign [Sa2 2:23], his name was probably given to this division in honor of his memory, and his son was invested with the command.

We have here an account of the regulation of the militia of the kingdom. David was himself a man of war, and had done great things with the sword; he had brought into the field great armies. Now here we are told how he marshalled them when God had given him rest from all his enemies. He did not keep them all together, for that would have been a hardship on them and the country; yet he did not disband and disperse them all, for then he would have left his kingdom naked, and his people would have forgotten the arts of war, wherein they had been instructed. He therefore contrived to keep up a constant force, and yet not a standing army. The model is very prudent. 1. He kept up 24,000 constantly in arms, I suppose in a body, and disciplined, in one part or other of the kingdom, the freeholders carrying their own arms and bearing their own charges while they were up. This was a sufficient strength for the securing of the public peace and safety. Those that are Israelites indeed must learn war; for we have enemies to grapple with, whom we are concerned constantly to stand upon our guard against. 2. He changed them every month; so that the whole number of the militia amounted to 288,000, perhaps about a fifth part of the able men of the kingdom. By being thus distributed into twelve courses, they were all instructed in, and accustomed to, military exercises; and yet none were compelled to be in service, and at expenses, above one month in the year (which they might very well afford), unless upon extraordinary occasions, and then they might all be got together quickly. It is the wisdom of governors, and much their praise, while they provide for the public safety, to contrive how to make it effectual and yet easy, and as little as possible burdensome to the people. 3. Every course had a commander in chief over it. Besides the subaltern officers that were rulers over thousands, and hundreds, and fifties, there was one general officer to each course or legion. All these twelve great commanders are mentioned among David's worthies and champions, 2 Sa. 23 and 1 Chr. 11. They had first signalized themselves by their great actions and then they were advanced to those great preferments. It is well with a kingdom when honour thus attends merit. Benaiah is here called a chief priest, Ch1 27:5. But, cohen signifying both a priest and a prince, it might better be translated here a chief ruler, or (as in the margin) a principal officer. Dodai had Mikloth (Ch1 27:4) either for his substitute when he was absent or infirm, or for his successor when he was dead. Benaiah had his son under him, Ch1 27:6. Asahel had his son after him (Ch1 27:7), and by this it seems that this plan of the militia was laid in the beginning of David's reign; for Asahel was killed by Abner while David reigned in Hebron. When his wars were over he revived this method, and left the military affairs in this posture, for the peaceable reign of his son Solomon. When we think ourselves most safe, yet, while we are here in the body, we must keep in a readiness for spiritual conflicts. Let not him that girdeth on the harness boast as he that puts it off.

Asahel the brother of Joab - This verse proves that the division and arrangement mentioned above were made before David was acknowledged king in Hebron; for Asahel, the brother of Joab, who was fourth captain, was slain by Abner, while Ishbosheth reigned over Israel at Mahanaim, Sa2 2:19-23.

Over the first course for the first month,.... The month Nisan, sometimes called Abib, which was March:

was Jashobeam the son of Zabdiel; the first and chief of David's worthies, 1 Chronicles 11:11.

and in his course were twenty and four; and so in all the following ones; this man was of the posterity of Perez, or Pharez, a son of Judah, and so had the preference and command of all the captains of the army for that month:

Dodai an Ahohite; the same with Dodo, 1 Chronicles 11:12 was over the course of the second month, the month Ziv, sometimes called Jiar, or April; and his lieutenant or successor was Mikloth:

Benaiah the son of Jehoiada, a chief priest; or rather a prince, a principal officer, was general of the army for the third month, Sivan, or May; the same was mighty among the thirty, and even above them, for he was among the three mighty, 1 Chronicles 11:22 and Ammizabad his son succeeded him, or was his deputy, when other ways employed: though led by our version here, and following the Jewish writers, I have called Benaiah a priest; see Gill on 1 Kings 2:31, yet I am now rather of opinion that he was not one; for though priests might bear arms on some occasions, yet it is not likely that one should be in a constant military office, and especially general of an army; and besides, this man was of Kabzeel, a city in the tribe of Judah, which is not mentioned among the Levitical cities, see 2 Samuel 23:20. Asahel the brother of Joab was over the course for the fourth month, Tammuz, or June, and who being slain by Abner, his son Zebadiah succeeded him: Shamhuth, the same with Shammah, 2 Samuel 23:11 and Shammoth, 1 Chronicles 11:27 was captain for the fifth month, Ab, or July: Ira the son of Ikkesh, the Tekoite, was over the course of the sixth month, Elul, or August, see 1 Chronicles 11:28. Helez the Pelonite was captain for the seventh month, Tisri, or September, see 1 Chronicles 11:27, the captain for the eighth month, Marchesvan, sometimes called Bul, or October, was Sibbecai the Hushathite, of the Zarbites, of the posterity of Zerah, a son of Judah in the line of Hushah, 1 Chronicles 4:4, the captain of the course for the ninth month, Cisleu, or November was Abiezer, of Anethoth, in the tribe of Benjamin, see 1 Chronicles 11:28, Maharai, of Netophah, in the tribe of Judah, and of the posterity of Zerah, was over the course for the tenth month, Tebet, or December, see 1 Chronicles 11:30 and the captain for the eleventh month, Sheber, or January, was Benaiah, of Pirathon, in the tribe of Ephraim, see 1 Chronicles 11:31 and over the course for the twelfth month, Adar, or February, was Heldai the Netophathite, the same with Heled, 1 Chronicles 11:30 and who was of the posterity of Othniel, the first judge in Israel, Judges 1:13.

Shamhuth; supposed to be the same called Shammah, , and Shammoth, .
