Exodus 12:48-50

Evangelical Heritage Version

⁴⁸ If a resident alien among you wants to observe the Passover to the Lord, every male in his household must be circumcised. Then he may take part in it. He will be treated like a native-born of the land. But no uncircumcised person may eat it. ⁴⁹ The same law will apply to the native-born and to the alien who resides among you.” ⁵⁰ So that is what all the Israelites did. They did just as the Lord commanded Moses and Aaron.
