Deuteronomy 11:19-21

You shall teach them to your children, speaking of them when you sit in your house, when you walk by the way, when you lie down, and when you rise up. And you shall write them on the doorposts of your house and on your gates, that your days and the days of your children may be multiplied in the land of which the LORD swore to your fathers to give them, like the days of the heavens above the earth.
