'Stretched Out His Hand' in the Bible

And Aaron stretched out his hand over the waters of Egypt, and the frogs came up and covered the land of Egypt.

And they did so. For Aaron stretched out his hand with his rod and struck the dust of the earth. And it became lice in man and in beast. All the dust of the land became lice throughout all the land of Egypt.

And Moses stretched out his hand over the sea. And Jehovah caused the sea to recede by a strong east wind all that night, and made the sea dry land, and the waters were divided.
