Charles Ellicott Commentary 2 Chronicles 29:8

"Wherefore the wrath of Jehovah was upon Judah and Jerusalem, and he hath delivered them to be tossed to and fro, to be an astonishment, and a hissing, as ye see with your eyes." — 2 Chronicles 29:8 (ASV)

The wrath ... was (i.e., fell) upon Judah. —This phrase is from 2 Chronicles 24:18. (Compare to 2 Chronicles 19:2; 2 Chronicles 19:10.)

Delivered them to trouble ... —Rather, made them a horror, an astonishment, and a hissing. The language is Deuteronomic. (Deuteronomy 28:37: “Thou shalt become a horror ... an astonishment.”Jeremiah 25:9; Jeremiah 25:18: “I will make them an astonishment and a hissing,” and elsewhere.)

As you see with your (own) eyes. —For you behold the disastrous results of the invasions of Aram and Israel, of Edom and the Philistines, and of the appeal to Assyria (2 Chronicles 28:0).
