Albert Barnes Commentary Ezekiel 37:1

"The hand of Jehovah was upon me, and he brought me out in the Spirit of Jehovah, and set me down in the midst of the valley; and it was full of bones." — Ezekiel 37:1 (ASV)

The valley - The same word as “the plain” (Ezekiel 3:22; Ezekiel 8:4). The “dry bones” represented the Israelites dispersed abroad, destitute of national and spiritual life.
