Deuteronomy 6:4-9

Listen, people of Israel, The Lord our God, the Lord is the only one. You shall love the Lord your God with all your mind and with all your being and with all your strength. The commands I'm giving you today must stay in your minds. You are to explain them carefully to your children and talk about them when you're at home and when you're traveling, when you lie down and when you get up. Tie them on your hands as reminders and put them on your foreheads as well. Write them on the doorposts of your homes and on your gates.
