Before the Lord - Abiathar and Zadok the priests were both with David, and the tabernacle and altar may have been at Hebron, though the ark was at Kirjath-jearim.

They anointed David king - This was the third time that David was anointed, having now taken possession of the whole kingdom.

So all the elders of Israel came to the king to Hebron,.... Which either explains what is meant by the tribes coming to him, 2 Samuel 5:1; namely, coming by their elders as their representatives; or else the meaning is, that the messengers the tribes sent, when they returned and reported the favourable reception they had met with from David; the elders of the several tribes, the princes or principal men met, and came together to David in Hebron:

and King David made a league with them before the Lord; the states of the nation; he entered into a covenant with them; he on his part promising to rule them in justice and judgment according to the laws, and they promising to yield a cheerful obedience to him in all things just and lawful: and this was done "before the Lord"; either before the ark of the Lord, as Abarbinel; but that was in Kirjathjearim, from whence it was after this brought by David to this city; rather, as Kimchi observes, wherever all Israel, or the greater part of them, were assembled, there the divine Shechinah or Majesty dwelt; so that what was done in a public assembly was reckoned as done before the Lord, and in his presence; or this covenant was made before the Lord, and each party appealed to him as witness of it, so that it was a very solemn one:

and they anointed David king over Israel; that is, over all Israel, which was the third time of his being anointed; the first was by Samuel, pointing out the person the Lord chose and appointed king; the second was by the tribe of Judah, when they invested him with the office of a king over them; and now by all the tribes, when he was inaugurated into the whole kingdom of Israel; and not only the elders came at this time, but great numbers of the people from the several tribes, and continued with David some days, eating, drinking and rejoicing, see 1 Chronicles 12:1.

"All the elders of Israel came" is a repetition of 2 Samuel 5:1, except that the expression "all the tribes of Israel" is more distinctly defined as meaning "all the elders of Israel." "So all the elders came; ... and king David made a covenant with them in Hebron before the Lord (see at 2 Samuel 3:21): and they anointed David king over (all) Israel." The writer of the Chronicles adds, "according to the word of the Lord through Samuel," i.e., so that the command of the Lord to Samuel, to anoint David king over Israel (1 Samuel 16:1, 1 Samuel 16:12), found its complete fulfilment in this.

So all the elders of Israel came to the king to Hebron; and king David made a league with them in Hebron {b} before the LORD: and they anointed David king over Israel.

(b) That is, taking the Lord to witness: for the ark was still in Abinadab's house.

5:3 A league - Whereby David obliged himself to rule them according to God's laws; and the people promised obedience to him.

3. King David made a league with them in Hebron before the Lord-(see on [260]1Sa 10:17). This formal declaration of the constitution was chiefly made at the commencement of a new dynasty, or at the restoration of the royal family after a usurpation (2Ki 11:17), though circumstances sometimes led to its being renewed on the accession of any new sovereign (1Ki 12:4). It seems to have been accompanied by religious solemnities.

5:1-5 David was anointed king a third time. His advances were gradual, that his faith might be tried, and that he might gain experience. Thus his kingdom typified that of the Messiah, which was to come to its height by degrees. Thus Jesus became our Brother, took upon him our nature, dwelt in it that he might become our Prince and Saviour: thus the humbled sinner takes encouragement from the endearing relation, applies for his salvation, submits to his authority, and craves his protection.
