Regarding the way in which he was slaughtered, the flowing blood was given as the price on behalf of those who are saved. And since he was crucified not on behalf of a portion or [on behalf] of one nation of men, he purchased by his blood [some] from every tribe of Israel and every language of men and indeed of [every] people.

Alternative translation:
Subsequent to the slaughter that was so executed, the blood that was shed was the price given for the redemption of those saved. Furthermore, since he was crucified for the sake of not just a part of humanity or of one nation only, he has redeemed by his blood people out of every tribe of Israel and of every human tongue, and, yes, of every people.
