Exodus 12:12-14

International Standard Version

¹² I’ll pass through the land of Egypt that night and strike every firstborn in the land of Egypt, both people and animals. I’ll execute judgments on all the gods of Egypt. I am the Lord. ¹³ The blood will be a sign for you on the houses where you are. I’ll see the blood and pass over you. There will be no plague to destroy you when I strike the land of Egypt.

¹⁴ “‘This day is to be a memorial for you, and you are to celebrate it as a festival to the Lord. You are to celebrate it as a perpetual ordinance from generation to generation.
