Exodus 12:44-49

44Any slave you have bought may eat it after you have circumcised him,

45but a temporary resident or a hired worker may not eat it.

46“It must be eaten inside the house; take none of the meat outside the house. Do not break any of the bones.

47The whole community of Israel must celebrate it.

48“A foreigner residing among you who wants to celebrate the Lord’s Passover must have all the males in his household circumcised; then he may take part like one born in the land. No uncircumcised male may eat it.

49The same law applies both to the native-born and to the foreigner residing among you.”
