Literary Context
This verse functions as the opening line for a short narrative-prophetic unit in Isaiah 20, providing a date marker and the triggering event. It shifts from broader oracles to a concrete moment: a named Assyrian king, a named official, and a named city. The writing slows down to locate the reader in real-world history before the passage moves (in the following verses) to Isaiah’s enacted sign and its meaning. The logic here is simple: this happened at that time, under that king, through that commander, at that city.
