Matthew Henry Commentary Proverbs 5:15-23

"Drink waters out of thine own cistern, And running waters out of thine own well. Should thy springs be dispersed abroad, And streams of water in the streets? Let them be for thyself alone, And not for strangers with thee. Let thy fountain be blessed; And rejoice in the wife of thy youth. [As] a loving hind and a pleasant doe, Let her breasts satisfy thee at all times; And be thou ravished always with her love. For why shouldest thou, my son, be ravished with a strange woman, And embrace the bosom of a foreigner? For the ways of man are before the eyes of Jehovah; And he maketh level all his paths. His own iniquities shall take the wicked, And he shall be holden with the cords of his sin. He shall die for lack of instruction; And in the greatness of his folly he shall go astray." — Proverbs 5:15-23 (ASV)

Lawful marriage is a means God has appointed to keep from these destructive vices. But we are not properly united, unless we attend to God's word, seeking his direction and blessing, and acting with affection.

Always remember that even though secret sins may escape the eyes of our fellow human beings, 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 by God to themselves, to go on in the way to destruction.
