Exodus 12:42-44

BRG Bible

⁴² 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.

⁴³ ¶ And the Lord said unto Moses and Aaron, This is the ordinance of the passover: There shall no stranger eat thereof:

⁴⁴ But every man’s servant that is bought for money, when thou hast circumcised him, then shall he eat thereof.
