…וָאֶשָּׂא אֶתְכֶם עַל כַּנְפֵי נְשָׁרִים וָאָבִא אֶתְכֶם אֵלָי (Shemot 19:4) This is my favorite verse in the Torah. The wings of eagles provide other examples of powerful yet loving imagery in the Torah:
Devarim 32:11. “As an eagle awakens its nest, hovering over its fledglings, it spreads its wings, taking them and carrying them on its pinions.”
יא. כְּנֶשֶׁר יָעִיר קִנּוֹ עַל גּוֹזָלָיו יְרַחֵף יִפְרֹשׂ כְּנָפָיו יִקָּחֵהוּ יִשָּׂאֵהוּ עַל אֶבְרָתוֹ:

A beautiful parallel to this protective, nurturing behavior of the eagle is drawn by R. Yitzchak Ginsburgh, as he notes the use of the same unique, but rare word (רחף) in the opening lines of the Torah:
“. . . our verse illustrates the eagle as hovering over his nest, expressing himself to his fledglings as the most gentle of creatures, manifesting perfect balance and stability. The verb for ‘hover’ rachef, is very rare in the Torah. One of its only other appearances is in the second verse of Genesis, ‘and the spirit of God hovered over the waters’.” (from The Music of Redemption, The Hovering Eagle)

Bereishit 1:2. “Now the earth was astonishingly empty, and darkness was on the face of the deep, and the spirit of God was hovering over the face of the water.”
ב. וְהָאָרֶץ הָיְתָה תֹהוּ וָבֹהוּ וְחשֶׁךְ עַל פְּנֵי תְהוֹם וְרוּחַ אֱלֹהִים מְרַחֶפֶת עַל פְּנֵי הַמָּיִם:
