Proverbs 2:17 (KJV 1900) — 17 Which forsaketh the guide of her youth, And forgetteth the covenant of her God.
The second characteristic of the strange woman is that she forsakes the guide of her youth. This may be the husband she married while young.
Her third characteristic is that she forgets the covenant she made with God earlier in her life. At some point she made a covenant with God to remain pure, to live according to God’s principles. Marriage is certainly a holy covenant. When a woman forgets her marriage covenant and forsakes the godly training she had when young, she becomes a “strange woman.”
