My son, if thou wilt receive my words, and keep my commandments by thee,

My son, forget not my law, but see that thine heart keep my commandments.

he taught me also, saying, "Let thine heart receive my words, keep my commandments, and thou shalt live.

Keep my commandments and my law, even as the apple of thine eye, and thou shalt live.
