Deuteronomy 11:18-21

18Fix these words of mine in your hearts and minds; tie them as reminders on your hands and bind them on your foreheads. 19Teach them to your children, speaking about them when you sit at home and when you walk along the road, when you lie down and when you get up. 20Write them on the doorposts of your houses and on your gates, 21so that as long as the heavens are above the earth, your days and those of your children may be multiplied in the land that the LORD swore to give your fathers.
