Exodus 12:43 in context
And it came to pass at the end of the 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.
It 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 observed of all the children of Israel in their generations.
And the LORD said unto Moses and Aaron, This is the ordinance of the passover: There shall no stranger eat thereof:
But every man’s servant that is bought for money, when thou hast circumcised him, then shall he eat thereof.
A foreigner and an hired servant shall not eat thereof.
