5:15-23 Lawful marriage is a means God has appointed to keep from these destructive vices. But we are not properly united, except as we attend to God's word, seeking his direction and blessing, and acting with affection. Ever remember, that though secret sins may escape the eyes of our fellow-creatures, yet a man's ways are before the eyes of the Lord, who not only sees, but ponders all his goings. Those who are so foolish as to choose the way of sin, are justly left of God to themselves, to go on in the way to destruction.
15-20. By figures, in which well, cistern, and fountain [Pr 5:15, 18] represent the wife, and rivers of waters [Pr 5:16] the children, men are exhorted to constancy and satisfaction in lawful conjugal enjoyments. In Pr 5:16, fountains (in the plural) rather denote the produce or waters of a spring, literally, "what is from a spring," and corresponds with "rivers of waters."
