Exodus 12:48-50

Amplified Bible, Classic Edition

⁴⁸ When a stranger sojourning with you wishes to keep the Passover to the Lord, let all his males be circumcised, and then let him come near and keep it; and he shall be as one that is born in the land. But no uncircumcised person shall eat of it.

⁴⁹ There shall be one law for the native-born and for the stranger or foreigner who sojourns among you.

⁵⁰ Thus did all the Israelites; as the Lord commanded Moses and Aaron, so did they.
