Deuteronomy 11:19-21

Teach them to your children, talking about them when you sit at home and when you walk along the road, when you lie down and when you get up. Write them on the door-frames of your houses and on your gates, so that your days and the days of your children may be many in the land that the LORD swore to give your ancestors, as many as the days that the heavens are above the earth.
