Exodus 19:4

Ye have seen what I did unto the Egyptians, and how I bare you on Eagle's wings — An high expression of the wonderful tenderness God shewed for them. It notes great speed; God not only came upon the wing for their deliverance, but he hastened them out, as it were upon the wing. Also that he did it with great ease, with the strength as well as with the swiftness of an eagle. They that faint not, nor are weary, are said to mount up with wings as eagles, Isaiah 40:31. Especially it notes God's particular care of them, and affection to them. Even Egypt was the nest in which these young ones were first formed as the embryo of a nation: when by the increase of their numbers they grew to some maturity, they were carried out of that nest. I brought you unto myself — They were brought not only into a state of liberty, but into covenant and communion with God. This, God aims at in all the gracious methods of his providence and grace, to bring us back to himself, from whom we have revolted, and to bring us home to himself, in whom alone we can be happy.
