It was a night of watching unto HaShem for bringing them out from the land of Egypt; this same night is a night of watching unto HaShem for all the children of Israel throughout their generations.
And HaShem said unto Moses and Aaron: 'This is the ordinance of the passover: there shall no alien eat thereof;
but every man's servant that is bought for money, when thou hast circumcised him, then shall he eat thereof.
A sojourner and a hired servant shall not eat thereof.
In 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.
All the congregation of Israel shall keep it.
And when a stranger shall sojourn with thee, and will keep the passover to HaShem, 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.
One law shall be to him that is homeborn, and unto the stranger that sojourneth among you.'
Thus did all the children of Israel; as HaShem commanded Moses and Aaron, so did they.
And it came to pass the selfsame day that HaShem did bring the children of Israel out of the land of Egypt by their hosts.
