וַיְהִי֩ כִשְׁמֹ֨עַ הַמֶּ֜לֶךְ אֶת־דְּבַ֣ר אִישׁ־הָאֱלֹהִ֗ים אֲשֶׁ֨ר קָרָ֤א עַל־הַמִּזְבֵּ֙חַ֙ בְּבֵֽית־אֵ֔ל וַיִּשְׁלַ֨ח יָרָבְעָ֧ם אֶת־יָד֛וֹ מֵעַ֥ל הַמִּזְבֵּ֖חַ לֵאמֹ֣ר ׀ תִּפְשֻׂ֑הוּ וַתִּיבַ֤שׁ יָדוֹ֙ אֲשֶׁ֣ר שָׁלַ֣ח עָלָ֔יו וְלֹ֥א יָכֹ֖ל לַהֲשִׁיבָ֥הּ אֵלָֽיו׃
Als der König das Wort des Gottesmannes hörte, das er gerufen gegen den Altar in Bet-El, streckte Jerobeam seine Hand vom Altar herab und rief: Greift ihn! Da verdorrte seine Hand, die er gegen jenen ausgestreckt hatte; er vermochte nicht, sie an sich zurückzuziehen.
Rashi
But his hand dried up [stiffened]. The Holy One Blessed Is He, avenged the honor of a righteous person more than His own honor. [When] he was standing and offering sacrifices to idols, his hand did not stiffen, yet, because of slandering the righteous person, his hand stiffened.4I.e., his hand became paralyzed. Yerovom had stretched out his hand to signal his servants to seize the man of God.—Metzudas Dovid
