Albert Barnes Commentary Exodus 10:19

"And Jehovah turned an exceeding strong west wind, which took up the locusts, and drove them into the Red Sea; there remained not one locust in all the border of Egypt." — Exodus 10:19 (ASV)

West wind - Literally, “a sea wind,” a wind blowing from the sea on the northwest of Egypt.

Red sea - The Hebrew has the “Sea of Suph”: the exact meaning of which is disputed. Gesenius renders it “rush” or “seaweed;” but it is probably an Egyptian word. A seaweed resembling wood is thrown up abundantly on the shores of the Red Sea. The origin of the name “Red” Sea is uncertain: (naturalists have connected it with the presence of red infusoria, Exodus 7:17).
