It will be an awful time for the Hebrew nation. There will be looting (v. 6:9) and the terrorizing throughout the land (vv. 22-26). The sins of Judah and Jerusalem provoked God to bring this desolating judgment upon them. Read the chapter and look at the six reasons for their punishment.
Their sins made their sacrifices unacceptable to God (v. 6:20), and He gave them up to their own ruin (v. 6:21).
Be wise today and always - stay right with God.
