“Hear, O Israel: The Lord our God, the Lord is one. 5 You shall love
the Lord your God with all your heart and with all your soul and with
all your might. 6 And these words that I command you today shall be
on your heart. 7 You shall teach them diligently to your children, 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. 8 You shall bind
them as a sign on your hand, and they shall be as frontlets between
your eyes. 9 You shall write them on the doorposts of your house and
on your gates. Deuteronomy 6:4-9
