Albert Barnes Commentary Jeremiah 33:13

"In the cities of the hill-country, in the cities of the lowland, and in the cities of the South, and in the land of Benjamin, and in the places about Jerusalem, and in the cities of Judah, shall the flocks again pass under the hands of him that numbereth them, saith Jehovah." — Jeremiah 33:13 (ASV)

Telleth - that is, counts the number of his sheep.
