Proverbs 7:2

Keep my commandments and live
Not the commandments of the law only, but the commandments of Christ; and even the doctrines of Christ are so called, as faith in him, and love to the saints, ( 1 John 3:23 ) ( John 14:21 John 14:23 ) ; which is the way to live comfortably, peaceably, pleasantly, and honourably; and my law as the apple of thine eye;
the doctrine of Christ, the law of the Lord, that goes out of Zion; which should be as dear to men as the apple of their eye, and as carefully preserved, that the least injury is not done to it; it should be kept inviolate.
