Deuteronomy 6:6-8

MKJV(i) 6 And these words which I command you this day shall be in your heart. 7 And you shall carefully teach them to your sons, and shall talk of them when you sit in your house and when you walk by the way, and when you lie down, and when you rise up. 8 And you shall bind them for a sign upon your hand, and they shall be as frontlets between your eyes.
