TSK · Exodus 14:16

You will also take in your hand this staff, with which you will do the signs.”

“When Pharaoh says to you,‘Do a miracle,’ and you say to Aaron,‘Take your staff and throw it down before Pharaoh,’ it will become a snake.”

Moses stretched out his hand toward the sea, and the LORD drove the sea apart by a strong east wind all that night, and he made the sea into dry land, and the water was divided.

“Take the staff and assemble the community, you and Aaron your brother, and then speak to the rock before their eyes. It will pour forth its water, and you will bring water out of the rock for them, and so you will give the community and their beasts water to drink.”

The LORD of Heaven’s Armies is about to beat them with a whip, similar to the way he struck down Midian at the rock of Oreb. He will use his staff against the sea, lifting it up as he did in Egypt.
