1 Kings 3:14

If thou wilt walk in my ways: this caution God gives him, lest his great wisdom should make him proud, or careless, or presumptuous, as if he were out of all danger; and to oblige him to more care and circumspection to avoid the snares and mischiefs to which so much prosperity and glory would probably expose him; and withal, to justify himself in case he should afterwards alter the course of his providence towards Solomon; and that when men are surprised with Solomon's dreadful fall, they might know it was no surprisal to God, but that he did foresee it, and would overrule it to his own glory one way or other.
