Drink water out of your own cistern, or water flowing from your own well.
Should your water flow in the streets? Your streams of water in the public squares? No, they should be yours alone and not to share with strangers.
Let your fountain be blessed and take pleasure in the wife of your youth.
As the loving doe and a graceful fawn, let her breasts always satisfy you and be lost in her love forever.
Why would you be infatuated with a forbidden woman, and embrace the breast of a stranger?
The ways of man are before the eyes of Jehovah and He considers all his doings.
A wicked man’s iniquities entrap him; he is entangled in the ropes of his own sin.
He will die because of a lack of discipline and be lost because of his great stupidity. Proverbs 5:15-23 S-S.org
Fountain: Usually used figuratively. Best comprehended against the great importance attached to water sources in Israel. The womb, e.g. is referred to not only as a fountain of blood but also as the fountain from which children issue (Theological Wordbook Abridged)
Forbidden woman: The basic thought is of non-acquaintance or non-relatedness. often in Proverbs as the adulteress. (Theological Wordbook Abridged)
