Deuteronomy 11:19-21

19Teach 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. 20Write them on the doorframes of your houses and on your gates,

21so that your days and the days of your children may be many in the land the LORD swore to give your ancestors, as many as the days that the heavens are above the earth.
