Deuteronomy 11:16-21

But be vigilant, lest you be seduced away and end up serving and worshiping other gods and GOD erupts in anger and shuts down Heaven so there’s no rain and nothing grows in the fields, and in no time at all you’re starved out—not a trace of you left on the good land that GOD is giving you. Place these words on your hearts. Get them deep inside you. Tie them on your hands and foreheads as a reminder. Teach them to your children. Talk about them wherever you are, sitting at home or walking in the street; talk about them from the time you get up in the morning until you fall into bed at night. Inscribe them on the doorposts and gates of your cities so that you’ll live a long time, and your children with you, on the soil that GOD promised to give your ancestors for as long as there is a sky over the Earth.
