Numbers 22:23

ותרא האתון AND THE SHE-ASS SAW [THE ANGEL] — but he did not see him, for the Holy One, blessed be He, gave an animal power to see more than the man, for just because he possesses sense his mind would become perturbed if he sees noxious beings. וחרבו שלופה בידו AND HIS SWORD DRAWN IN HIS HAND — He (God) said: This wicked man has abandoned the tools of his own craft, — for the offensive weapons of the heathen peoples consist in the sword, — and he is attacking them with his mouth which is their metier; I will take his implement and come against him with his own metier. Thus, indeed, was his end (Numbers 31:8): “And Balaam the son of Beor they slew by the sword” (Midrash Tanchuma 4:7:23).

וַתֵּ֣רֶא הָאָתוֹן֩ אֶת־מַלְאַ֨ךְ יְהֹוָ֜ה נִצָּ֣ב בַּדֶּ֗רֶךְ וְחַרְבּ֤וֹ שְׁלוּפָה֙ בְּיָד֔וֹ וַתֵּ֤ט הָֽאָתוֹן֙ מִן־הַדֶּ֔רֶךְ וַתֵּ֖לֶךְ בַּשָּׂדֶ֑ה וַיַּ֤ךְ בִּלְעָם֙ אֶת־הָ֣אָת֔וֹן לְהַטֹּתָ֖הּ הַדָּֽרֶךְ׃

And the ass saw the angel of the Lord standing in the way, and his sword drawn in his hand: and the ass turned aside out of the way, and went into the field: and Bil῾am smote the ass, to turn her into the way.
