“Let her breasts fill you at all times with delight; be intoxicated always in her love” (Prov. 5:19) emphasizes two things: the quality of lovemaking (“fill… with delight” and “be intoxicated”) and the quantity of lovemaking (“at all times” and “always”). The wisdom of God is saying, “When you get married, drop your inhibitions, and go for it.” Back in the days of the Puritans, when a New England wife complained, first to her pastor and then to the whole congregation, that her husband was neglecting their sex life, the church removed him as a member. Why? Because the Bible is clear: “The wife does not have authority over her own body, but the husband does. Likewise the husband does not have authority over his own body, but the wife does. Do not deprive one another” (1 Cor. 7:4-5). And Proverbs 5 is wisely adding, “Make it fun and frequent!” The word translated “be intoxicated” is used elsewhere in the Old Testament for a man staggering down the street in drunkenness (Isa. 28:7). The point is for a man to be crazy in love with his wife. This counsel is not trivial. It is the serious wisdom of God, because, as we shall see later in the Bible, marriage points ultimately to the love of Christ and our joy in him. And the striking thing about this wisdom here in Proverbs, coming from ancient times as it does, is that marriages back then could be arranged for economic or political reasons. But the Bible sweeps all of that aside and calls husbands and wives to be head-over-heels in love with each other.”
