Matthew Poole and continuators on Genesis 17:14

14 And the uncircumcised man-child, whose Flesh of his fore-skin is not circumcised , that soul shall be cut of from his People : He hath broken my Covenant .

Or, rather, And as for the uncircumcised man-child. So the nominative is put absolutely, as is frequent in the Hebrew Tongue.

Or, Who shall not circumcise the Flesh of his fore-skin: For the Hebrew verb may be rendred actively: Which seems best here; because the punishment seems more justly to belong to the Parent, who was guilty of this neglect, than to the Child, who was not capable of this precept, and therefore not guilty of the violation of it. And this may further appear from Exod. 4. 24, 25. where God seeks to kill, not the Child, but the Father, Moses, for this sin. And the Flesh of the Childs Foreskin is rightly called the Flesh of his, i. e. The Parents Foreskin, because the Child is a part and the possession of his Parent. So that this threatning concerns only grown persons, and of them only such as shall willfully and unnecessarily neglect this duty: For otherwise it was neglected by the Israelites for forty years together in the Wilderness, Ios. 5. 7. without any token of Gods displeasure for it.

This phrase denotes either 1. An exclusion from fellowship with Gods People, and from all the promises, priviledges and blessings belonging to them either in this Life or that to come. Or rather 2. An untimely and violent death, as may be gathered from Exod. 31. 14. to be inflicted by the Magistrate, to whom God committed the execution of this, as well as other Laws, and in case of his neglect and default, or the secrecy of the fact, by the extraordinary hand of God, who sometimes ascribes this act to himself, as Levit. 17. 10. and 20. 6.

That sacred bond which tyed him and me together, and by his neglect and contempt of the condition required on his part, he hath forfeited the blessing promised on my part.
