Proverbs 20:5

Pro 20:5 Counsel in the heart of man [is like] deep water; but a man of understanding will draw it out.

Ver. 5. Counsel in the heart of man is like deep water. ] See Proverbs 18:4 . As the red rose, though outwardly not so fragrant, is inwardly far more cordial than the damask rose, being more thrifty of its sweetness, and reserving it in itself; so it is with many good Christians.

But a man of understanding will draw it out. ] And surely this is a fine skill to be able to pierce a man that is like a vessel full of wine, and to set him a running.
