Deuteronomy 6;6-9
6 These commandments that I give you today will be on your heart;
7 you shall instill them in your children, and you shall talk about them when you sit in your house, and when you go by the way, and when you lie down, and when you get up.
8 You shall bind them on your hand as a sign, and you shall place them on your forehead between your eyes
9 and you shall write them on the doorposts of your house and on the gates of your city.
