Deuteronomy 6:7-12

You shall teach them diligently to your children, and shall talk of them when you sit in your house, when you walk by the way, when you lie down, and when you rise up. You shall bind them as a sign on your hand, and they shall be as frontlets between your eyes. You shall write them on the doorposts of your house and on your gates. “So it shall be, when the LORD your God brings you into the land of which He swore to your fathers, to Abraham, Isaac, and Jacob, to give you large and beautiful cities which you did not build, houses full of all good things, which you did not fill, hewn-out wells which you did not dig, vineyards and olive trees which you did not plant—when you have eaten and are full— then beware, lest you forget the LORD who brought you out of the land of Egypt, from the house of bondage.
