Deuteronomy 6:5

2 That thou mightest fear the LORD thy God, to keep all his statutes and his commandments, which I command thee, thou, and thy son, and thy son’s son, all the days of thy life; and that thy days may be prolonged.

3 Hear therefore, O Israel, and observe to do [it]; that it may be well with thee, and that ye may increase mightily, as the LORD God of thy fathers hath promised thee, in the land that floweth with milk and honey.

4 Hear, O Israel: The LORD our God [is] one LORD:

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

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

7 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.

8 And thou shalt bind them for a sign upon thine hand, and they shall be as frontlets between thine eyes.
