The Hebrew abarah refers to the long feathers or pinions of a bird's wing — specifically the powerful flight feathers. It appears in the context of the eagle's wing in Job.
The eagle's pinions become in Scripture an image of God's protective power and Israel's redemption. God tells Moses: "I carried you on eagles' wings" (Exodus 19:4). Isaiah promises that those who wait on the LORD will "soar on wings like eagles" (Isaiah 40:31). The great pinion — the flight feather that makes soaring possible — becomes a picture of divine enabling. We do not soar by our own strength but by being carried on the wings of God.
