Parallel
Isaiah 27:1
Jewish Publication Society 1917 · Berean Standard Bible
In that day the LORD with his sore and great and strong sword will punish leviathan the slant serpent, and leviathan the tortuous serpent; and He will slay the dragon that is in the sea.
In that day the LORD will take His sharp, great, and mighty sword, and bring judgment on Leviathan the fleeing serpent (note: Hebrew nachash; translated in most cases as snake; twice in this verse)—Leviathan the coiling serpent—and He will slay the dragon of the sea.
