TSK · Exodus 7:9

And the LORD said unto him, What [is] that in thine hand? And he said, A rod.

And thou shalt take this rod in thine hand, wherewith thou shalt do signs.

And Moses and Aaron went in unto Pharaoh, and they did so as the LORD had commanded: and Aaron cast down his rod before Pharaoh, and before his servants, and it became a serpent.

And Moses stretched forth his rod over the land of Egypt, and the LORD brought an east wind upon the land all that day, and all [that] night; [and] when it was morning, the east wind brought the locusts.

Ask thee a sign of the LORD thy God; ask it either in the depth, or in the height above.

But he answered and said unto them, ‹An evil and adulterous generation seeketh after a sign; and there shall no sign be given to it, but the sign of the prophet Jonas:›

They said therefore unto him, What sign shewest thou then, that we may see, and believe thee? what dost thou work?
