Charles Ellicott Commentary Psalms 55:6

"And I said, Oh that I had wings like a dove! Then would I fly away, and be at rest." — Psalms 55:6 (ASV)

Oh that I had. —Literally, who will give me? —The bird that was in the psalmist’s thought was doubtless the Rock Pigeon (Columba livia), which selects for its nesting the lofty cliffs and deep ravines far from the neighborhood of man. (Compare to Song of Solomon 2:14, Note.)

Be at rest. —So the Septuagint and Vulgate, and the reading is consecrated by long use; but the parallelism seems to require the more literal dwell or abide.
