Exodus 17:5

So Moses and Aaron did thus, as Yahweh had commanded. And he raised 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.

“As for you, raise up your staff and stretch out your hand over the sea and split it, and the sons of Israel shall go through the midst of the sea on dry land.

“Take the rod; and you and your brother Aaron assemble the congregation and speak to the rock before their eyes, that it may yield its water. You shall thus bring forth water for them out of the rock and let the congregation and their beasts drink.”

You split open spring and river; You dried up ever-flowing rivers.

Do not harden your hearts, as at Meribah, As in the day of Massah in the wilderness,
