Deuteronomy 6:7-12

and thou shalt teach them diligently unto thy children, and shalt talk of them when thou sittest in thine house, and when thou walkest by the way, and when thou liest down, and when thou risest up. And thou shalt bind them for a sign upon thine hand, and they shall be for frontlets between thine eyes. And thou shalt write them upon the door posts of thy house, and upon thy gates. And it shall be, when the LORD thy God shall bring thee into the land which he sware unto thy fathers, to Abraham, to Isaac, and to Jacob, to give thee; great and goodly cities, which thou buildedst not, and houses full of all good things, which thou filledst not, and cisterns hewn out, which thou hewedst not, vineyards and olive trees, which thou plantedst not, and thou shalt eat and be full; then beware lest thou forget the LORD, which brought thee forth out of the land of Egypt, out of the house of bondage.
