That the Lord may continue his word - The original promise given to David indirectly, through Nathan 2 Samuel 7:11-17, and apparently unconditional, afterward was made conditional upon continued obedience. (See the margin reference "f.") David reminds Solomon of this, in order to impress upon him a powerful motive to continue faithful and obedient.

That the Lord may continue his word - The prosperity which God has promised to grant to my family will depend on their faithfulness to the good they receive; if they live to God, they shall sit for ever on the throne of Israel. But alas! they did not; and God's justice cut off the entail made by his mercy.

That the Lord may continue his word which he spake concerning me,.... his word of promise concerning the kingdom of David, and the succession of it, and confirm and establish it:

saying, if thy children take heed to their way; they are directed to walk in, even the way of the Lord, and not turn to the right hand or the left:

to walk before me in truth: in the sincerity and integrity of their hearts, according to the word of truth, and under the influence of the spirit of truth:

with all their heart, and with all their soul; in the most cordial manner, with the strongest affection and zeal; with all eagerness and earnestness; with their whole hearts engaged in every duty performed by them: then the Lord said,

there shall not fail thee a man on the throne of Israel; one to succeed him in the throne; this, with respect to his throne, literally considered, was conditional; but, spiritually considered, was absolute, and had its fulfilment in the Messiah, whose throne is for ever; see Luke 1:32.

Solomon would then experience still further this blessing of walking in the ways of the Lord, since the Lord would fulfil to him His promise of the everlasting possession of the throne. וגו יקים למען is grammatically subordinate to תּשׂכּיל למען in 1 Kings 2:3. The word which Jehovah has spoken concerning David (עלי דּבּר) is the promise in 2 Samuel 7:12., the substance of which is quoted here by David with a negative turn, וגו יכּרת לא, and with express allusion to the condition on which God would assuredly fulfil His promise, viz., if the descendants of David preserve their ways, to walk before the Lord in truth. בּאמת is more precisely defined by נפשׁם...בּכל. For the fact itself see Deuteronomy 5:5; Deuteronomy 11:13, Deuteronomy 11:18. The formula וגו יכּרת לא is formed after 1 Samuel 2:33 (compare also 2 Samuel 3:29 and Joshua 9:23). "There shall not be cut off to thee a man from upon the throne of Israel," i.e., there shall never be wanting to thee a descendant to take the throne; in other words, the sovereignty shall always remain in thy family. This promise, which reads thus in 2 Samuel 7:16, "Thy house and thy kingdom shall be continual for ever before thee, and thy throne stand fast for ever," and which was confirmed to Solomon by the Lord Himself after his prayer at the consecration of the temple (1 Kings 8:25; 1 Kings 9:5), is not to be understood as implying that no king of the Davidic house would be thrust away from the throne, but simply affirms that the posterity of David was not to be cut off, so as to leave no offshoot which could take possession of the throne. Its ultimate fulfilment it received in Christ (see at 2 Samuel 7:12.). The second לאמר in 2 Samuel 7:4 is not to be erased as suspicious, as being merely a repetition of the first in consequence of the long conditional clause, even though it is wanting in the Vulgate, the Arabic, and a Hebrew codex.

After a general admonition David communicated to his successor a few more special instructions; viz., first of all (2 Samuel 7:5, 2 Samuel 7:6), to punish Joab for his wickedness. "What Joab did to me:" - of this David mentions only the two principal crimes of Joab, by which he had already twice deserved death, namely, his killing the two generals. Abner (2 Samuel 3:27) and Amasa the son of Jether (2 Samuel 20:10). The name יתר is written יתרא in 2 Samuel 17:25. Joab had murdered both of them out of jealousy in a treacherous and malicious manner; and thereby he had not only grievously displeased David and bidden defiance to his royal authority, but by the murder of Abner had exposed the king to the suspicion in the eyes of the people of having instigated the crime (see at 2 Samuel 3:28, 2 Samuel 3:37). דּמי מ ויּשׂם "and he made war-blood in peace," i.e., he shed in the time of peace blood that ought only to flow in war (שׂים in the sense of making, as in Deuteronomy 14:1; Exodus 10:2, etc.), "and brought war-blood upon his girdle which was about his loins, and upon his shoes under his feet," sc. in the time of peace. This was the crime therefore: that Joab had murdered the two generals in a time of peace, as one ought only to slay his opponent in time of war. Girdle and shoes, the principal features in oriental attire when a man is preparing himself for any business, were covered with blood, since Joab, while saluting them, had treacherously stabbed both of them with the sword. David ought to have punished these two crimes; but when Abner was murdered, he felt himself too weak to visit a man like Joab with the punishment he deserved, as he had only just been anointed king, and consequently he did nothing more than invoke divine retribution upon his head (2 Samuel 3:29). And when Amasa was slain, the rebellions of Absalom and Sheba had crippled the power of David too much, for him to visit the deed with the punishment that was due. But as king of the nation of God, it was not right for him to allow such crimes to pass unpunished: he therefore transferred the punishment, for which he had wanted the requisite power, to his son and successor.

That the LORD may continue his word which he spake concerning me, saying, If thy children take heed to their way, to walk before me in {c} truth with all their heart and with all their soul, there shall not fail thee (said he) a man on the throne of Israel.

(c) Without hypocrisy.

2:4 Confirm his word - Fulfil his promise, the condition upon which it was suspended, being performed.

fail...: Heb. be cut off from thee from the throne

4. there shall not fail thee . a man on the throne of Israel-a reference to the promise made to David of the sovereignty being vested perpetually in his lineage (2Sa 7:11-16), which was confirmed to Solomon afterwards (see 1Ki 9:5), and repeated with reference to its spiritual meaning long after (Jer 33:17).

2:1-4 David's charge to Solomon is, to keep the charge of the Lord. The authority of a dying father is much, but nothing to that of a living God. God promised David that the Messiah should come from his descendants, and that promise was absolute; but the promise, that there should not fail of them a man on the throne of Israel, was conditional; if he walks before God in sincerity, with zeal and resolution: in order hereunto, he must take heed to his way.
