John Gill Commentary 2 Kings 21:12

"therefore thus saith Jehovah, the God of Israel, Behold, I bring such evil upon Jerusalem and Judah, that whosoever heareth of it, both his ears shall tingle." — 2 Kings 21:12 (ASV)

Therefore thus says the Lord God of Israel
Who, though kind and gracious to Israel as their covenant God, is yet just and righteous, as well as he is a sovereign Being and Lord of all:

behold, I am bringing such evil upon Jerusalem and Judah, that
whoever hears of it, both his ears will tingle ;
it will make such a noise in the world, and be so horrible and terrible; and if, the report of it would be so dreadful as to make a man's ears tingle, and his heart tremble, what must it be to endure it! (Ezekiel 22:14) (1 Samuel 3:11) .
