Deuteronomy 6:6

Write these commandments that I’ve given you today on your hearts. Get them inside of you and then get them inside your children. Talk about them wherever you are, sitting at home or walking in the street; talk about them from the time you get up in the morning to when you fall into bed at night. Tie them on your hands and foreheads as a reminder; inscribe them on the doorposts of your homes and on your city gates.
