51 Ex 7:19 Then the LORD said to Moses, "Say to Aaron, 'Take your staff and stretch out your hand over the waters of Egypt, over their rivers, over their streams, and over their pools, and over all their reservoirs of water, that they may become blood; and there will be blood throughout all the land of Egypt, both in vessels of wood and in vessels of stone.'"
52 Ex 7:20 So Moses and Aaron did even as the LORD had commanded. And he lifted up the staff and struck the water that was in the Nile, in the sight of Pharaoh and in the sight of his servants, and all the water that was in the Nile was turned to blood.
54 Ex 8:5 Then the LORD said to Moses, "Say to Aaron, 'Stretch out your hand with your staff over the rivers, over the streams and over the pools, and make frogs come up on the land of Egypt.'"
55 Ex 8:8 Then Pharaoh called for Moses and Aaron and said, "Entreat the LORD that He remove the frogs from me and from my people; and I will let the people go, that they may sacrifice to the LORD."
56 Ex 8:9 Moses said to Pharaoh, "The honor is yours to tell me: when shall I entreat for you and your servants and your people, that the frogs be destroyed from you and your houses, that they may be left only in the Nile?"
59 Ex 8:16 Then the LORD said to Moses, "Say to Aaron, 'Stretch out your staff and strike the dust of the earth, that it may become gnats through all the land of Egypt.'"
