Counsel in the heart of man is like deep water; but a man of understanding will draw it out.
– Proverbs 20:5
[T]he word for counsel means purpose and refers to inner intentions, or motives. The image of deep water is also used in Proverbs 18:4, and the meaning is consistent here. It refers to what is hidden, or beneath the surface. (For further explanation of the image, see commentary on Proverbs 18:4). What lies in the heart of men is hidden, but a man of understanding discovers it. The word for understanding means discernment. The point of proverbs is “To give subtilty to the simple, to the young man knowledge and discretion” (Proverbs 1:4). In other words, Proverbs teaches wisdom to those who will receive it. Wisdom discerns motives and true character hidden behind facades, or in this image, in deep water.
