12 “I will pass throughk the land of Egypt on that night and strike every firstborn male in the land of Egypt, both people and animals. I am the Lord; I will execute judgments against all the gods of Egypt.l 13 The blood on the houses where you are staying will be a distinguishing mark for you; when I see the blood, I will pass over you. No plague will be among you to destroy you when I strike the land of Egypt.

14 “This day is to be a memorial for you, and you must celebrate it as a festival to the Lord. You are to celebrate it throughout your generations as a permanent statute.m
