Exodus 7:17-20 Expanded Bible (EXB)
17 This is what the Lord says: ‘This is how you will know that I am the Lord. I will strike the water of the Nile River with this ·stick [staff] in my hand, and the water will change into blood. 18 Then the fish in the Nile will die, and the river will begin to stink. The Egyptians will not be able to drink the water from the Nile.’”
19 The Lord said to Moses, “Tell Aaron: ‘Take the ·walking stick [staff] in your hand and stretch your hand over the rivers, canals, ponds, and pools in Egypt.’ The water will become blood everywhere in Egypt, both in wooden buckets and in stone jars.”
20 So Moses and Aaron did just as the Lord had commanded. In front of ·the king [L Pharaoh] and his officers, Aaron raised his ·walking stick [staff] and struck the water in the Nile River. So all the water in the Nile changed into blood.
