Jeremiah 6:26-28

King James Version

²⁶ O daughter of my people, gird thee with sackcloth, and wallow thyself in ashes: make thee mourning, as for an only son, most bitter lamentation: for the spoiler shall suddenly come upon us.

²⁷ I have set thee for a tower and a fortress among my people, that thou mayest know and try their way.

²⁸ They are all grievous revolters, walking with slanders: they are brass and iron; they are all corrupters.
