Deu 11:18-21
Fix these words of mine in your hearts and minds; tie them as symbols on your hands and bind them on your foreheads. 19 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. 20 Write them on the doorframes of your houses and on your gates, 21 so that your days and the days of your children may be many in the land that the LORD swore to give your forefathers, as many as the days that the heavens are above the earth.
