Deuteronomy 10:12-20

12And now, Israel, what doth the LORD thy God require of thee, but to fear the LORD thy God, to walk in all his ways, and to love him, and to serve the LORD thy God with all thy heart and with all thy soul, 13To keep the commandments of the LORD, and his statutes, which I command thee this day for thy good? 14Behold, the heaven and the heaven of heavens belongeth to the LORD thy God, the earth also, with all that is in it. 15Only the LORD had a delight in thy fathers to love them, and he chose their seed after them, even you above all people, as it is this day. 16Circumcise therefore the foreskin of your heart, and be no more stiffnecked. 17For the LORD your God is God of gods, and Lord of lords, a great God, a mighty, and a terrible, who regardeth not persons, nor taketh reward: 18He executeth the judgment of the fatherless and widow, and loveth the stranger, in giving him food and raiment. 19Love ye therefore the stranger: for ye were strangers in the land of Egypt. 20Thou shalt fear the LORD thy God; him shalt thou serve, and to him shalt thou cleave, and swear by his name.
