'Cast down' in the Bible

When Pharaoh shall speak to you, saying, Give ye a wonder for you; and say to Aaron, Take thy rod and cast down before Pharaoh, it shall be into a dragon.

And Moses and Aaron went in to Pharaoh, and did so, as Jehovah had commanded; and Aaron cast down his staff before Pharaoh, and before his bondmen, and it became a serpent.

they cast down every man his staff, and they became serpents; but Aaron's staff swallowed up their staves.
