2 Kings 18:35

that the Lord should deliver Jerusalem Rab-shakeh should have had a better memory. In verse 25 he said he had the Lord's command to destroy Jerusalem; but here, forgetful, he speaks of the same Lord as one who might be expected to defend it.

Or does he only speak ex concesso, taking the ground of those whom he addresses? Theythought the Lord would deliver. -If you do think so", would then be his meaning, -what reason have you for your belief"?
