Exodus 12:48-49 ▼

48 “But if a stranger sojourns with you, and celebrates the Passover to the LORD, let all his males be circumcised, and then let him come near to celebrate it; and he shall be like a native of the land. But no uncircumcised person may eat of it.

49 “The same law shall apply to the native as to the stranger who sojourns among you.”
