Exodus 12:48-50

New Catholic Bible

⁴⁸ “If a foreigner dwells among you and wishes to celebrate the Passover of the Lord, let each man in his household be circumcised. Then let him draw near to celebrate and he will be like a native of the land. But no one who is uncircumcised can eat it. ⁴⁹ The same law will be binding on the native and the foreigner who is living in your midst.”

⁵⁰ All the children of Israel did just as the Lord had commanded Moses and Aaron.
