שָׁא֣וּל וִיהוֹנָתָ֗ן הַנֶּאֱהָבִ֤ים וְהַנְּעִימִם֙ בְּחַיֵּיהֶ֔ם וּבְמוֹתָ֖ם לֹ֣א נִפְרָ֑דוּ מִנְּשָׁרִ֣ים קַ֔לּוּ מֵאֲרָי֖וֹת גָּבֵֽרוּ׃
Saul and Jonathan, the lovely and the pleasant In their lives, even in their death they were not divided; They were swifter than eagles, They were stronger than lions.
Rashi on II Samuel
They were lighter then eagles. To do the will of their Creator.20Rashi is paraphrasing Pirkei Avos 5,23.
