Deuteronomy 6:4-15

4Hear, O Israel: Jehovah our God is one Jehovah: 5and thou shalt love Jehovah thy God with all thy heart, and with all thy soul, and with all thy might. 6And these words, which I command thee this day, shall be upon thy heart; 7and thou shalt teach them diligently unto thy children, and shalt talk of them when thou sittest in thy house, and when thou walkest by the way, and when thou liest down, and when thou risest up. 8And thou shalt bind them for a sign upon thy hand, and they shall be for frontlets between thine eyes. 9And thou shalt write them upon the door-posts of thy house, and upon thy gates.

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. 13Thou shalt fear Jehovah thy God; and him shalt thou serve, and shalt swear by his name. 14Ye shall not go after other gods, of the gods of the peoples that are round about you; 15for Jehovah thy God in the midst of thee is a jealous God; lest the anger of Jehovah thy God be kindled against thee, and he destroy thee from off the face of the earth.
