Some Jewish believers are trying to force you to perform certain rituals so that other Jews will think highly of them. They are insisting that you be circumcised {that someone must circumcise you}. They are doing that only in order that other Jews would no longer ◄persecute them/cause them to suffer► for proclaiming that God will save us because of our trusting in what Christ accomplished when he died on the cross [MTY, MET].
