Exodus 12:27-29

Wycliffe Bible

²⁷ ye shall say to them, It is the sacrifice of the passing (over) of the Lord, when he passed over the houses of the sons of Israel in Egypt, and smote the Egyptians, and delivered our houses (but spared our houses). And the people was bowed, and worshipped.

²⁸ And the sons of Israel went out (And the Israelites went out), and did as the Lord commanded to Moses and Aaron.

²⁹ Forsooth it was done in the midst of the night, the Lord smote all the first begotten thing(s) in the land of Egypt, from the first begotten of Pharaoh, that sat in the throne of him (who sat on his throne), till to the first begotten of a captive woman, that was in (the) prison, and all the first engendered of beasts.
