19 ^tYou shall teach them to your children, talking of them when you are sitting in your house, and when you are walking by the way, and when you lie down, and when you rise. 20 ^uYou shall write them on the doorposts of your house and on your gates, 21 that your days and the days of your children may be multiplied in the land that the Lord swore to your fathers to give them, as long as the heavens are above the earth.
