אָ֣ז יְדַלֵּ֤ג כָּֽאַיָּל֙ פִּסֵּ֔חַ וְתָרֹ֖ן לְשׁ֣וֹן אִלֵּ֑ם כִּֽי־נִבְקְע֤וּ בַמִּדְבָּר֙ מַ֔יִם וּנְחָלִ֖ים בָּעֲרָבָֽה׃
Alors le boiteux bondira comme le chamois, la langue du muet entonnera des chants; car des sources d’eau jaillissent dans le désert, des rivières dans la plaine aride.
Rashi on Isaiah
Then the lame shall skip like a hart, etc. Israel, who are now lame and weak. We find that he calls the weak with an expression of ‘lame,’ as the matter is stated (above 33:23): “The lame take the prey.”
Ibn Ezra on Isaiah
Then shall the lame man leap, in his return to Jerusalem.
