’Thus saith Sennacherib king of Assyria: Whereon do ye trust, that ye abide the siege in Jerusalem?
Rashi on II Chronicles
In what do you trust It is written (I Kings 18:5): “He trusted in the Lord God of Israel,” and it is also written there: (verse 7) “and he rebelled against the king of Assyria.” Therefore, he asked, “In what do you trust” that you have rebelled against me?
Rashi on II Chronicles
stay in the siege in Jerusalem as it is written (here): “to die by famine and thirst.”
