And leaves the guide of her youth, etc. It is clear about the adulteress because she first leaves her husband and forgets the covenant of her God, evidently that which she made with her husband, with the Lord as witness, at the time of marriage, that they would keep the faith of chastity with each other. It is also clear about the heretical mind, because it leaves the teacher from whom it learned the faith of the Church; and forgets the covenant of its God, that is, of the Lord's own faith, which is contained in the creed, which it promised to keep on the day of baptism.
[AD 735] Bede on Proverbs 2:17
