Ye have seen what I did unto the Egyptians, and how I bare you on {d} eagles' wings, and brought you unto myself.

(d) For the eagle by flying high, is out of danger, and by carrying her birds on her wings rather than in her talons declares her love.

Wesley's Notes

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, Isa 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.

Matthew Henry's Concise Commentary

19:1-8 Moses was called up the mountain, and was employed as the messenger of this covenant. The Maker and first Mover of the covenant, is God himself. This blessed charter was granted out of God's own free grace. The covenant here mentioned was the national covenant, by which the Israelites were a people under the government of Jehovah. It was a type of the new covenant made with true believers in Christ Jesus; but, like other types, it was only a shadow of good things to come. As a nation they broke this covenant; therefore the Lord declared that he would make a new covenant with Israel, writing his law, not upon tables of stone, but in their hearts, Jer 31:33; Heb 8:7-10. The covenant spoken of in these places as ready to vanish away, is the national covenant with Israel, which they forfeited by their sins. Unless we carefully attend to this, we shall fall into mistakes while reading the Old Testament. We must not suppose that the nation of the Jews were under the covenant of works, which knows nothing of repentance, faith in a Mediator, forgiveness of sins, or grace; nor yet that the whole nation of Israel bore the character, and possessed the privileges of true believers, as being actually sharers in the covenant of grace. They were all under a dispensation of mercy; they had outward privileges and advantages for salvation; but, like professing Christians, most rested therein, and went no further. Israel consented to the conditions. They answered as one man, All that the Lord hath spoken we will do. Oh that there had been such a heart in them! Moses, as a mediator, returned the words of the people to God. Thus Christ, the Mediator, as a Prophet, reveals God's will to us, his precepts and promises; and then, as a Priest, offers up to God our spiritual sacrifices, not only of prayer and praise, but of devout affections, and pious resolutions, the work of his own Spirit in us.
