Exodus 12:48-50

Common English Bible

⁴⁸ If an immigrant who lives with you wants to observe the Passover to the Lord, then he and all his males should be circumcised. Then he may join in observing it. He should be regarded as a native of the land. But no uncircumcised person may eat it. ⁴⁹ There will be one Instruction for the native and for the immigrant who lives with you.

⁵⁰ All the Israelites did just as the Lord had commanded Moses and Aaron.
