Proverbs 2:17

Which forsaketh the guide of her youth
Not God, the God of her life, and who had provided for her from her youth up; nor her parent that had taken care of her in her infancy, and had been the guardian of her virgin state; but her husband, to whom she was married in her youth, and to whom she gave up herself to be guided and directed, ruled and governed, by: and as it is an aggravation of evil in a man to deal treacherously against the wife of his youth, and the wife of his covenant, ( Malachi 2:14 ) ; so it is in a woman to forsake "the friend" or "companion of her youth" ^F23, as the phrase may be rendered; who loved her and espoused her in his youthful age, and with whom he had lived long in love and friendship, and in great happiness, but now forsakes him; her affections being alienated from him, leaves his company and bed, and associates with others. Gersom interprets this of the human understanding, appointed to govern the other powers and faculties of the soul; and forgetteth the covenant of her God:
not the covenant made with Noah, in which adultery, as well as other things, were forbidden; nor the law of Moses, or covenant at Sinai, in which it was condemned; but the marriage covenant, which she entered into with her husband when espoused to him, and when they mutually obliged themselves to be faithful to one another: and this is called "the covenant of God"; not only because God is the author and institutor of marriage, and has directed and enjoined persons to enter into such a contract with one another; but because he is present at it, and is a witness of such an engagement, mid is appealed unto in it; which, as it adds to the solemnity of it, makes the violation of it the more criminal. So the church of Rome has forsook Christ, who was her guide in her first settlement, and her husband she professed to be espoused to, as a chaste virgin; and has followed other lovers, and become the mother of harlots; so false teachers leave their guide, the Scriptures, and bring in damnable heresies, and deny the Lord that bought them, ( 2 Peter 2:1 ) .
