Deuteronomy 6:9 (KJV)

Hear, O Israel: The LORD our God is one LORD:

And thou shalt love the LORD thy God with all thine heart, and with all thy soul, and with all thy might.

And these words, which I command thee this day, shall be in thine heart:

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 as frontlets between thine eyes.

And it shall be, when the LORD thy God shall have brought 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 wells digged, which thou diggedst not, vineyards and olive trees, which thou plantedst not; when thou shalt have eaten and be full;

Then beware lest thou forget the LORD, which brought thee forth out of the land of Egypt, from the house of bondage.

Thou shalt fear the LORD thy God, and serve him, and shalt swear by his name.

Ye shall not go after other gods, of the gods of the people which are round about you;
