Charles Ellicott Commentary 2 Chronicles 15:5

"And in those times there was no peace to him that went out, nor to him that came in; but great vexations were upon all the inhabitants of the lands." — 2 Chronicles 15:5 (ASV)

And in those times. — The “many days” (Compare to 2 Chronicles 15:3); the times of national unfaithfulness.

There was no peace ... came in. — (Judges 5:11; Judges 6:11.)

But great vexations. — For great confusions (mehûmôth). (See Deuteronomy 28:20, where mehûmah, “confusion” or “discomfiture,” is foretold as a punishment of apostasy.) Here the meaning seems to be tumults, as in Amos 3:9. “The countries” are the territories or provinces of Israel, as in 2 Chronicles 34:33.
