Bind them continually upon thine heart, and tie them about thy neck.
Let not mercy and truth forsake thee: bind them about thy neck; write them upon the table of thine heart:
Forsake her not, and she shall preserve thee: love her, and she shall keep thee.
Let them not depart from thine eyes; keep them in the midst of thine heart.
Bind them upon thy fingers, write them upon the table of thine heart.
Say unto wisdom, Thou art my sister; and call understanding thy kinswoman:
And it shall be for a token upon thine hand, and for frontlets between thine eyes: for by strength of hand the LORD brought us forth out of Egypt.
And thou shalt bind them for a sign upon thine hand, and they shall be as frontlets between thine eyes.
2 Corinthians 3:3
Forasmuch as ye are manifestly declared to be the epistle of Christ ministered by us, written not with ink, but with the Spirit of the living God; not in tables of stone, but in fleshy tables of the heart.
