The lion is come up from his thicket, and the destroyer of the Gentiles is on his way; he is gone forth from his place to make thy land desolate; and thy cities shall be laid waste, without an inhabitant.

For this gird you with sackcloth, lament and howl: for the fierce anger of the LORD is not turned back from us.
