Exodus 12:40-51

40Now the sojourning of the children of Israel, which they sojourned in Egypt, was four hundred and thirty years. 41And it came to pass at the end of four hundred and thirty years, even the selfsame day it came to pass, that all the hosts of the LORD went out from the land of Egypt. 42It is a night to be much observed unto the LORD for bringing them out from the land of Egypt: this is that night of the LORD, to be much observed of all the children of Israel throughout their generations. 43And the LORD said unto Moses and Aaron, This is the ordinance of the passover: there shall no alien eat thereof: 44but every man’s servant that is bought for money, when thou hast circumcised him, then shall he eat thereof. 45A sojourner and an hired servant shall not eat thereof. 46In one house shall it be eaten; thou shalt not carry forth aught of the flesh abroad out of the house; neither shall ye break a bone thereof. 47All the congregation of Israel shall keep it. 48And when a stranger shall sojourn with thee, and will keep the passover to the LORD, let all his males be circumcised, and then let him come near and keep it; and he shall be as one that is born in the land: but no uncircumcised person shall eat thereof. 49One law shall be to him that is homeborn, and unto the stranger that sojourneth among you. 50Thus did all the children of Israel; as the LORD commanded Moses and Aaron, so did they. 51And it came to pass the selfsame day, that the LORD did bring the children of Israel out of the land of Egypt by their hosts.
