The second plague of Egypt was frogs. God commanded Moses to tell Aaron to stretch the staff over the water, and hordes of frogs came and over ran Egypt. Pharaoh's sorcerers were also able to duplicate this plague with their magic. However, since they were unable to remove it, Pharaoh was forced to grant permission for the Israelites to leave so that Moses would agree to remove the frogs. To prove that the plague was actually a divine punishment, Moses let Pharaoh choose the time that it would end. Pharaoh chose the following day, and all the frogs died the next day. Nevertheless, Pharaoh rescinded his permission, and the Israelites stayed in Egypt.
