Exodus 12:48-50

Darby Translation

⁴⁸ And when a sojourner sojourneth with thee, and would hold the passover to Jehovah, let all his males be circumcised, and then let him come near and hold it; and he shall be as one that is born in the land; but no uncircumcised person shall eat thereof.

⁴⁹ One law shall be for him that is home-born and for the sojourner that sojourneth among you.

⁵⁰ And all the children of Israel did as Jehovah had commanded Moses and Aaron; so did they.
