Exodus 12:48-49 ▼

48 “If there are foreigners living among you who want to celebrate the LORD’s Passover, let all their males be circumcised. Only then may they celebrate the Passover with you like any native-born Israelite. But no uncircumcised male may ever eat the Passover meal.

49 This instruction applies to everyone, whether a native-born Israelite or a foreigner living among you.”
