Exodus 12:48

The Voice

⁴⁸ If you have outsiders living among you and they want to celebrate the Passover to the Eternal with you, then all the men must agree to be circumcised. Only after circumcision may they join in and celebrate with you; then you must treat them as if they were native-born. But make sure no uncircumcised male eats any part of the sacred meal.
