Proverbs 2:16 To deliver thee from the strange woman, even from the stranger which flattered with her words.
The promises based upon the condition of listening to God and His Word of wisdom continue. Wisdom is Jesus and wisdom is believing in Jesus. Seeking knowledge is studying the Bible, for in it we find Christ to whom the Scriptures testify. If you hear the Word of Law and Gospel God will use it to deliver you from prostitutes and whorish women who appeal to a man’s lust.
Refraining from illicit sexual relationships and shunning immorality may not seem like a wonderful thing to our sinful nature, but it is. Chastity does feel like a valuable and beneficial blessing, but it is. A “strange woman” is a metaphor for a person to whom one is not married who tempts his lustful desire for an illicit physical relationship. She is “strange” in that she is not a believer in Christ (or at least a Christian who is not acting like a Christian). She is outside the Christian fellowship. “Her paths incline unto death.” This is serious, and it is not a “victimless” crime.
There is no redeeming value in prostitution, no blessing in it, no promise of anything good. Avoiding sex outside of a committed marriage does hold the promise of a blessed life. Marital bliss is a wonderful blessing and a great promise.
In addition, the “strange woman” metaphor is more broadly speaking a metaphor for worldly pleasures of all kinds. And the world will try to lead us away from God, and that’s not good. So God is good to give us the Word and the Spirit to deliver us from the deathly evil of the world and it’s death and into the Kingdom and it’s life.
