And he gave him - That is, God appointed or commanded this, Genesis 17:9-13.
The covenant - The word “covenant” denotes properly “a compact or agreement between two or more persons,” usually attended with seals, pledges, or sanctions. In Genesis 17:7, and elsewhere, it is said that God would establish his “covenant” with Abraham; that is, he made him certain definite promises, attended with pledges and seals, etc. The idea of a strict “compact” or “agreement” between God and man, as between “equal parties”; is not found in the Bible. The word is commonly used, as here, to denote “a promise on the part of God,” attended with pledges, and demanding, on the part of man, in order to avail himself of its benefits, a specified course of conduct. The “covenant” is therefore another name for denoting two things on the part of God:
- A “command,” which man is not at liberty to reject, as he would be if it were a literal covenant; and,
- A “promise,” which is to be fulfilled only on the condition of obedience. The covenant with Abraham was simply a “promise” to give him the land, and to make him a great nation, etc. It was never proposed to Abraham with the supposition that he was at liberty to reject it, or to refuse to comply with its conditions. Circumcision was appointed as the mark or indication that Abraham and those thus designated were the persons included in the gracious purpose and promise. It served to separate them as a special people; a people whose unique characteristic it was that they obeyed and served the God who had made the promise to Abraham. The phrase “covenant of circumcision” means, therefore, the covenant or promise which God made to Abraham, of which circumcision was the distinguishing “mark” or “sign.”
The twelve patriarchs - The word “patriarch” properly denotes “the father and ruler of a family.” But it is commonly applied, by way of eminence, to “the progenitors” of the Jewish race, particularly to “the twelve sons of Jacob.” See the notes on Acts 2:29.
