Deuteronomy 6:10-12

10And it shall be, when Jehovah 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 buildest not, 11and 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; 12then beware lest thou forget Jehovah, who brought thee forth out of the land of Egypt, out of the house of bondage.
