13:22 beasts of the islands. This part of Babylon’s “burden” will probably be fulfilled after the rebuilt Babylon sinks beneath the sea (Jeremiah 51:42,64; Revelation 18:21). The previous verse describes its habitation by “wild beasts of the desert,” this portion being fulfilled in the long centuries following her first collapse into ruins.
13:22 dragons. The “dragons” (Hebrew tannin) are the “sea monsters,” probably marine dinosaur-like reptiles, or great sea serpents (note Isaiah 27:1), that still survive in the deep ocean. It is nothing but evolutionary fantasy that assumes such monsters died out aeons before man appeared on the earth.
