A fractal image reminiscent of eagles wings, along with the text of Exodus 19:4, "You saw what I did to the Egyptians, and how I bore you on eagles' wings, and brought you unto Myself." Add your own text.
Many have attempted to answer the question as to why Hashem chose the imagery of an eagle ? The eagle is not even a kosher bird. Perhaps it was to express His unconditional love for us Rashi's comment is perhaps most famous. "All other birds carry their young in their talons, out of fear of a larger predator attacking them from behind and above. The eagle, however, fears no other bird, only man. For this reason it carries its young on its wings, reasoning that if it is attacked by arrows, it would suffer the injury, not their young. When the Egyptians attacked the Jews at the Red Sea, G‑d sent angels to situate themselves between the camp of Israel and the Egyptian camp, and the Divine clouds absorbed the missiles and arrows." A couple of other comments: "I bore you on eagles' wings." The effect of the image is, of course, to convey intimacy, protection, love, speed; but also, I suggest, the enormous power of the adult eagle, effortlessly carrying its young through the air. In other words, it engenders in the people a sense of their own lightness. It deflates their grandiosity and evokes a relation to God, in which their kavod, their weightiness, becomes insignificant. (Aviva Gottlieb Zornberg, The Particulars of Rapture: Reflections on Exodus, Doubleday, 2001, p. 258) "I bore you on eagles' wings" so that now you no longer have any human master above you. Hence you are now in a position to accept the sovereignty of the Kingdom of Heaven, and I expect you to hearken to My voice. (Shem MiShmuel/Rabbi Abraham Bornstein, cited by Alexander Zusia Friedman in Wellsprings of Torah, Judaica Press, 1980) The imagery of eagles wings was also used for Isaiah 40:31: Those who trust in the Lord will renew their strength. They will soar on wings like eagles.
