Deuteronomy 6:3-9

Hear therefore, O Israel, and observe them diligently, so that it may go well with you, and so that you may multiply greatly in a land flowing with milk and honey, as the LORD, the God of your ancestors, has promised you. Hear, O Israel: The LORD is our God, the LORD alone. You shall love the LORD your God with all your heart, and with all your soul, and with all your might. Keep these words that I am commanding you today in your heart. Recite them to your children and talk about them when you are at home and when you are away, when you lie down and when you rise. Bind them as a sign on your hand, fix them as an emblem on your forehead, and write them on the doorposts of your house and on your gates.
