Deuteronomy

Ye shall diligently keep the commandments of the Lord your God, and his testimonies, and his statutes, which he hath commanded thee.

Thou shalt fear the Lord thy God; him shalt thou serve, and to him shalt thou cleave, and swear by his name.

Thou hast commanded us to keep thy precepts diligently.

But take diligent heed to do the commandment and the law, which Moses the servant of the Lord charged you, to love the Lord your God, and to walk in all his ways, and to keep his commandments, and to cleave unto him, and to serve him with all your heart and with all your soul.

And it shall come to pass, if ye shall hearken diligently unto my commandments which I command you this day, to love the Lord your God, and to serve him with all your heart and with all your soul,
