Exodus 12:43-47

The LORD said to Moses and Aaron, “These are the regulations for the Passover meal: “No foreigner may eat it. Any slave you have bought may eat it after you have circumcised him, but a temporary resident or a hired worker may not eat it. “It must be eaten inside the house; take none of the meat outside the house. Do not break any of the bones. The whole community of Israel must celebrate it.
