Proverbs 5:15-20
By figures, in which well, cistern, and fountain [Proverbs 5:15, Proverbs 5:18] represent the wife, and rivers of waters [Proverbs 5:16] the children, men are exhorted to constancy and satisfaction in lawful conjugal enjoyments. In Proverbs 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."
