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 Luk 1:32.

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 (Sa2 7:11-16), which was confirmed to Solomon afterwards (see Kg1 9:5), and repeated with reference to its spiritual meaning long after (Jer 33:17).
