The PINION — the long, strong flight-feather of a wing, not soft down. Psalm 91:4, 'with his evrah he will cover you,' is the parent bird mantling over the young, the same picture as the eagle of Deuteronomy 32:11 and the hen of Matthew 23:37. The point of the precise word is that the covering feather is the one built for flying, not for warmth. → first discussed at Psalms 91:4
