Easton's Bible Dictionary: M. G. Easton, M.A., D.D.
A moral rather than an intellectual quality. To be "foolish" is to be godless (Ps. 14:1; comp. Judg. 19:23; 2 Sam. 13:13). True wisdom is a gift from God to those who ask it (Job 28:12-28; Pr. 3:13-18; Rom. 1:22, 16:27; 1 Cor. 1:17-21, 2:6-8; Jas. 1:5). "Wisdom" in Pr. 1:20, 8:1, 9:1-5 may be regarded not as a mere personification of the attribute of wisdom, but as a divine person, "Christ the power of God and the wisdom of God" (1 Cor. 1:24). In Mt. 11:19 it is the personified principle of wisdom that is meant.
