and he received the sign of circumcision, a seal of the righteousness of the faith which he had while uncircumcised, so that he might be the father of all who believe without being circumcised, that righteousness might be counted to them,
“Moreover Yahweh your God will circumcise your heart and the heart of your seed, to love Yahweh your God with all your heart and with all your soul, so that you may live.
