Whereupon the ass exclaimed: Am I not your ass upon whom thou hast ridden from my very youth unto this day?!” (so you see, you have never possessed a horse) — as it is related in Treatise Avodah Zarah 4b.

וַתֹּ֨אמֶר הָאָת֜וֹן אֶל־בִּלְעָ֗ם הֲלוֹא֩ אָנֹכִ֨י אֲתֹֽנְךָ֜ אֲשֶׁר־רָכַ֣בְתָּ עָלַ֗י מֵעֽוֹדְךָ֙ עַד־הַיּ֣וֹם הַזֶּ֔ה הַֽהַסְכֵּ֣ן הִסְכַּ֔נְתִּי לַעֲשׂ֥וֹת לְךָ֖ כֹּ֑ה וַיֹּ֖אמֶר לֹֽא׃
