As an eagle stirreth up her nest, that fluttereth over her young - Deuteronomy 32:11

Three references are made to the eagle in this passage. She stirs up her nest. - When her fledglings are old enough to fly, but linger around the few bits of stick, dignified as a nest, the mother-bird breaks it up, and scatters them. How much better this, than that they should miss the luxury of flight on outspread pinions in the blue vault, and of basking in the eye of the sun. So when the Father sees His children clinging to earth's bare rocks, captured and held by the poor sticks they have gathered, and missing the ascension-glory, He breaks up the nest. The fortune is dispersed, the home broken up, the aspect of the life changed. We are then able to enjoy the bliss of life in the heavenlies with Christ Jesus.
 
She flutters aver her young. - They stand scared and wretched on the edge of the rock, but she careers gently above them, now edging around, now mounting, then dropping far below to rise again. So would she allure them to follow her example. Here again we have an emblem of God's efforts to make us imitators of Himself, to teach us the possibilities that await us in Jesus.
 
She spreads forth her wings and takes them. - Incited by the mother's endeavors, the eaglet may venture on the untried air, and lo! the unaccustomed wings fail beneath its weight. It falls, but not far, for the mother swoops beneath, and bears it up and away. Trembling soul, God is beneath thee. If thy faith fails, and thou art falling, like another Peter, into a bottomless abyss, He will catch thee, and bear thee up, and teach thee the mystery of the more abundant life.
