As the Israelites were camped by Sinai, Moses went on the mountain and there God spoke to him about the pact He would ratify with the people (Jacob and Israel were synonyms for the nation). God compared His delivering the people out of Egypt, across the Red (Reed) Sea, and to Sinai to His carrying them on eagles’ wings (Deut. 32:10-11). When young eagles are learning to fly, the mother eagle flies under them with her wings spread out to catch them.
I bore you on eagles’ wings, a high expression of the wonderful tenderness God had shown for them. It is explained, Deu. 32:11, 12. It denotes great speed. God not only came upon the wing for their deliverance (when the set time was come, he rode on a cherub, and did fly), but he hastened them out, as it were, upon the wing. He did it also with great ease, with the strength as well as with the swiftness of an eagle: those that faint not, nor are weary, are said to mount up with wings as eagles, Isa. 40:31. Especially, it denotes God’s particular care of them and affection to them. Even Egypt, that iron furnace, was the nest in which these young ones were hatched, where they 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. Other birds carry their young in their talons, but the eagle (they say) upon her wings, so that even those archers who shoot flying cannot hurt the young ones, unless they first shoot through the old one. Thus, in the Red Sea, the pillar of cloud and fire, the token of God’s presence, interposed itself between the Israelites and their pursuers (lines of defense which could not be forced, a wall which could not be penetrated): yet this was not all; their way so paved, so guarded, was glorious, but their end much more so: I brought you unto myself. They were brought not only into a state of liberty and honor, but into covenant and communion with God. Henry, Matthew, Matthew Henry’s Commentary on the Bible,
