This continues the king of Assyria's message to Hezekiah. The chief commander is speaking the message to Hezekiah's men. (See: [Isaiah 36:4-5](./04.md))
This speaks of Egypt, specifically its army and its Pharaoh, as if it were a splintered reed to emphasize that relying on them would not help them but would only harm them. Alternate translation: "that is like walking with a splintered reed for a staff. If a man leans on it, it will stick into his hand and pierce it" (See: [[rc://en/ta/man/translate/figs-metaphor]])
The king of Assyria uses this question to ridicule the people and to imply that Yahweh was angry about what Hezekiah did and would not protect them. This rhetorical question can be translated as a statement. Alternate translation: "he is the one whose high places and altars Hezekiah has taken away ... Jerusalem." or "he is the one whom Hezekiah insulted by tearing down his high places and altars ... Jerusalem."
