He shall cover thee with his feathers, and under his wings shalt thou trust: his truth [shall be thy] shield and buckler.
Ver. 4. He shall cover thee with his feathers] As the hen doth her chickens; Fides est quae te pullastrum, Christum gallinam facit, ut sub pennis eius speres; nam salus in pennis eius, saith Luther; it is faith which maketh thee the little chicken, and Christ the hen; that thou mayest hide, and hope, and hover, and cover under his wings; for there is health in his wings.
And under his wings shalt thou trust] For without faith what use is there to us of the promises. Non de se debet sperare Christianus; si vult esse firmus vapore materno nutriatur, ut pullus gallinaceus, saith Austin; Let no man hope for safety or strength but under Christ's wings graciously stretched out over him.
