The depth saith - This is a beautiful personification. The object of this verse and the following is, to show that wisdom cannot be found in the deepest recesses to which man can penetrate, nor purchased by anything which man possesses. It must come from God only. The word “depth” here (תהום tehôm) means properly a wave, billow, surge; then a mass of waters, a flood, or the deep ocean, Deuteronomy 8:7; Genesis 7:11; Psalms 36:6; and then a gulf, or abyss. It refers here to the sea, or ocean; and the idea is, that its vast depths might be sounded, and true wisdom would not be found there.
