'Stretched Out His Hand' in the Bible

But the Lord said to Moses, “Reach out your hand and grasp it by the tail.” So he reached out his hand and caught it, and it became a staff in his hand—

So Aaron stretched out his hand [with his staff] over the waters of Egypt, and the frogs came up and covered the land of Egypt.

They did so; Aaron stretched out his hand with his staff and struck the dust of the earth, and there were [biting] gnats on man and animal. All the dust of the land became gnats through all the land of Egypt.

So Moses stretched out his hand toward the sky, and for three days a thick darkness was all over the land of Egypt [no sun, no moon, no stars].

Then Moses stretched out his hand over the sea; and the Lord swept the sea back by a strong east wind all that night and turned the seabed into dry land, and the waters were divided.
