Albert Barnes Commentary Jeremiah 33:12

"Thus saith Jehovah of hosts: Yet again shall there be in this place, which is waste, without man and without beast, and in all the cities thereof, a habitation of shepherds causing their flocks to lie down." — Jeremiah 33:12 (ASV)

An habitation - “A shepherd’s encampment.” The words, causing their flocks to lie down, mean gathering them into the fold at night.
