Albert Barnes Commentary Ezekiel 7:16

"But those of them that escape shall escape, and shall be on the mountains like doves of the valleys, all of them moaning, every one in his iniquity." — Ezekiel 7:16 (ASV)

As doves whose natural home is the valleys moan mournfully when driven by fear into the mountains, so will the remnant, who have escaped actual death, moan in the land of their exile.
