What does Jeremias Chapter 6 say, and which statements belong to its speaker?

Jeremias 6 tells Benjamin's sons to strengthen themselves in Jerusalem, sound Thecua's trumpet and raise Bethacarem's standard against northern evil. Sion is likened to a beautiful, delicate woman, not a pasture. Shepherds and flocks encamp around her, followed by midday war preparation, lengthening evening shadows and a night attack on houses. Trees are cut and a trench cast about oppressive Jerusalem. A cistern cooling water illustrates cooling wickedness, with violence, spoil, infirmity and stripes; instruction is urged lest she become uninhabited.

Vine gleaning describes gathering Israel's remains. Uncircumcised ears reject the word; held-in fury is poured on child, youth council, man, woman and aged. Houses, lands and wives pass to others. Covetousness and prophet-priest deceit accompany disgraceful healing of the breach with Peace, peace where none exists. Failure to blush precedes falling. The Lord commands inquiry about old paths and walking the good way for soul refreshment; they refuse, as they refuse watchmen's trumpet. Nations and earth hear evils as fruits of thoughts and rejected law. Saba's incense, distant sweet cane and unacceptable offerings precede destruction of fathers, sons, neighbors and kinsmen.

The cruel northern nation takes arrow and shield, roars like sea and rides horses. Heard fame weakens hands and causes labor-like anguish. Fields and highways are unsafe; sackcloth and sprinkled ashes accompany mourning like an only son's and sudden destroyer. A strong trier proves ways; deceitful princes are brass and iron. Bellows fail, lead burns and melting is vain because wicked deeds remain, producing the name reprobate silver. Fire signals, flight outward, siege ladders, spears, wallowing ashes and permanent incorrigibility are not supplied.
