I will lengthen thy days - The promise here was only conditional. As the condition was not observed 1 Kings 11:1-8, the right to the promise was forfeited, and it was not fulfilled. Solomon can scarcely have been more than fifty-nine or sixty at his death.

And if thou wilt walk in my ways,.... Prescribed and directed to in his word,

to keep my statutes and my commandments; ceremonial, moral, and judicial:

as thy father David did walk; which Solomon himself had observed, 1 Kings 3:6; and whose walk was worthy of his imitation:

then I will lengthen thy days; the other promises of riches and honour are absolute, but this of long life conditional, depending upon his holy walk and conversation; and hence, because he failed in this the Jews observe he did not attain to long life, dying, as they suppose, at fifty two years of age; which is grounded on a wrong hypothesis, that he was but twelve years of age when he he began to reign, and he reigned forty years, as before observed.

And if thou wilt walk in my ways, to keep my statutes and my commandments, as thy father David did walk, then I will lengthen thy days.

3:14 And if - This caution God gives him, lest his wisdom should make him proud, careless, or presumptuous.

3:5-15 Solomon's dream was not a common one. While his bodily powers were locked up in sleep, the powers of his soul were strengthened; he was enabled to receive the Divine vision, and to make a suitable choice. God, in like manner, puts us in the ready way to be happy, by assuring us we shall have what we need, and pray for. Solomon's making such a choice when asleep, and the powers of reason least active, showed it came from the grace of God. Having a humble sense of his own wants and weakness, he pleads, Lord, I am but a little child. The more wise and considerate men are, the better acquainted they are with their own weakness, and the more jealous of themselves. Solomon begs of God to give him wisdom. We must pray for it, Jas 1:5, that it may help us in our particular calling, and the various occasions we have. Those are accepted of God, who prefer spiritual blessings to earthly good. It was a prevailing prayer, and prevailed for more than he asked. God gave him wisdom, such as no other prince was ever blessed with; and also gave him riches and honour. If we make sure of wisdom and grace, these will bring outward prosperity with them, or sweeten the want of it. The way to get spiritual blessings, is to wrestle with God in prayer for them. The way to get earthly blessings, is to refer ourselves to God concerning them. Solomon has wisdom given him, because he did ask it, and wealth, because he did not.
