Deuteronomy 12:28

Thou shalt keep therefore his statutes, and his commandments, which I command thee this day, that it may go well with thee, and with thy children after thee, and that thou mayest prolong thy days upon the earth, which the Lord thy God giveth thee, for ever.

If ye keep my commandments, ye shall abide in my love; even as I have kept my Father’s commandments, and abide in his love.

Ye are my friends, if ye do whatsoever I command you.

And as for thee, if thou wilt walk before me, as David thy father walked, and do according to all that I have commanded thee, and shalt observe my statutes and my judgments;

Thou shalt not eat it; that it may go well with thee, and with thy children after thee, when thou shalt do that which is right in the sight of the Lord.

Take heed in the plague of leprosy, that thou observe diligently, and do according to all that the priests the Levites shall teach you: as I commanded them, so ye shall observe to do.

Observe thou that which I command thee this day: behold, I drive out before thee the Amorite, and the Canaanite, and the Hittite, and the Perizzite, and the Hivite, and the Jebusite.

And David my servant shall be king over them; and they all shall have one shepherd: they shall also walk in my judgments, and observe my statutes, and do them.

Now ye are clean through the word which I have spoken unto you.

Therefore shall ye observe all my statutes, and all my judgments, and do them: I am the Lord.

And said, I beseech thee, O Lord God of heaven, the great and terrible God, that keepeth covenant and mercy for them that love him and observe his commandments:

That they might observe his statutes, and keep his laws. Praise ye the Lord.
