Exodus 12:42-49

42It is a night of observance to Jehovah, because of their being brought out from the land of Egypt: that same night is an observance to Jehovah for all the children of Israel in their generations.

43And Jehovah said to Moses and Aaron, This is the ordinance of the passover: No stranger shall eat of it;

44but every man's bondman that is bought for money — let him be circumcised: then shall he eat it.

45A settler and a hired servant shall not eat it.

46In one house shall it be eaten; thou shalt not carry forth any of the flesh abroad out of the house; neither shall ye break a bone thereof.

47All the assembly of Israel shall hold it.

48And when a sojourner sojourneth with thee, and would hold the passover to Jehovah, let all his males be circumcised, and then let him come near and hold it; and he shall be as one that is born in the land; but no uncircumcised person shall eat thereof.

49One law shall be for him that is home-born and for the sojourner that sojourneth among you.
