I do not know what Mr. N. means by a double account of the origin of circumcision; I know of but one, that in Gen. 17 It is referred to Elohim, but He is called, as appearing to Abraham, Jehovah, and yet gives His name as ΕΙ-Shaddaí. It was a command connected with the character and nature of God. They were to be a separate people to Him, and the flesh be mortified. This "was not of Moses," who brought in specially the name Jehovah as the ground of relationship, "but of the fathers," antecedent to the special relationship of the Jews with Him, and connected with the name "God Almighty," that Abraham might be a father of many nations.
