Deuteronomy 7:6

They were bound to do this by virtue of their election as a holy nation, the nation of possession, which Jehovah had singled out from all other nations, and brought out of the bondage of Egypt, not because of its greatness, but from love to them, and for the sake of the oath given to the fathers. This exalted honour Israel was not to cast away by apostasy from the Lord. It was founded upon the word of the Lord in Exo 19:5-6, which Moses brought to the recollection of the people, and expressly and emphatically developed. "Not because of your multitude before all nations (because ye were more numerous than all other nations) hath Jehovah turned to you in love (חשׁק, to bind oneself with, to hang upon a person, out of love), for ye are the littleness of all nations" (the least numerous). Moses could say this to Israel with reference to its descent from Abraham, whom God chose as the one man out of all the world, whilst nations, states, and kingdoms had already been formed all around (Baumgarten). "But because Jehovah loved you, and kept His oath which He had sworn to the fathers, He hath brought you out," etc. Instead of saying, He hath chosen you out of love to your fathers, as in Deu 4:37, Moses brings out in this place love to the people of Israel as the divine motive, not for choosing Israel, but for leading it out and delivering it from the slave-house of Egypt, by which God had practically carried out the election of the people, that He might thereby allure the Israelites to a reciprocity of love.

Moses in this chapter exhorts Israel, I. In general, to keep God's commandments (Deu 7:11, Deu 7:12). II. In particular, and in order to that, to keep themselves pure from all communion with idolaters. 1. They must utterly destroy the seven devoted nations, and not spare them, or make leagues with them (Deu 7:1, Deu 7:2, Deu 7:16, Deu 7:24). 2. They must by no means marry with the remainders of them (Deu 7:3, Deu 7:4). 3. They must deface and consume their altars and images, and not so much as take the silver and gold of them to their own use (Deu 7:5, Deu 7:25, Deu 7:26). To enforce this charge, he shows that they were bound to do so, (1.) In duty. Considering [1.] Their election to God (Deu 7:6). [2.] The reason of that election (Deu 7:7, Deu 7:8). [3.] The terms they stood upon with God (Deu 7:9, Deu 7:10). (2.) In interest. It is here promised, [1.] In general, that, if they would serve God, he would bless and prosper them (Deu 7:12-15). [2.] In particular, that if they would drive out the nations, that they might not be a temptation to them, God would drive them out, that they should not be any vexation to them (Deu 7:17, etc.).

7:6 Of all peoples on earth, God chose Israel as his special treasure. Israel had not done anything commendable; rather, God acted out of grace that was undeserved and freely given.
