Exodus 12:10-12 Modern English Version (MEV)
10 And you shall let nothing of it remain until the morning, but that of it which remains until the morning you shall burn with fire. 11 In this way shall you eat it: with your waist girded, your sandals on your feet, and your staff in your hand. So you shall eat it in haste. It is the Lord’s Passover.
12 For I will pass through the land of Egypt this night and will smite all the firstborn in the land of Egypt, both man and beast, and against all the gods of Egypt I will execute judgment. I am the Lord.
