Deuteronomy 32:11

Her nest — Her young ones in the nest; which she by her cry and motion provoketh to fly. Her wings — As preparing herself to fly. On her wings — Or, as on her wings, that is, gently, and tenderly and safely too, as if she carried them not in her claws for fear of hurting them, but upon her wings. Some say, the eagle doth usually carry her young ones upon her wings.
