"This particular text was written in the wake of the Assyrian invasion of Judah and the siege of Jerusalem by Sennacherib in 703-701 BC (20 years after he had already wiped out Israel). Here the author resorts to hyperbole (exaggeration) in describing the utter destruction of the land of Judah: that is, the destruction of Judah is envisioned as the destruction of the whole earth. 2 Kings 18:13-17 briefly alludes to this destruction."
With this interpretation, how does it effect the next verse? Genesis 8:22 -While the earth remaineth, seedtime and harvest, and cold and heat, and summer and winter, and day and night shall not cease.
