A man of Elokim came from Yehuda, and Yeravam was standing on the mizbeach.
וְהִנֵּה אִישׁ אֱלֹקִים בָּא מִיהוּדָה בִּדְבַר ה' אֶל בֵּית אֵל וְיָרׇבְעָם עֹמֵד עַל הַמִּזְבֵּחַ לְהַקְטִיר׃

"And behold, a man of Elokim came from Yehuda by the word of Hashem to Beis El, and Yeravam was standing on the mizbeach to burn incense."
Melachim Aleph 13:1
Seize him! And his hand dried up.
וַיִּשְׁלַח יָרׇבְעָם אֶת יָדוֹ מֵעַל הַמִּזְבֵּחַ לֵאמֹר תִּפְשֻׂהוּ וַתִּיבַשׁ יָדוֹ אֲשֶׁר שָׁלַח עָלָיו וְלֹא יָכֹל לַהֲשִׁיבָהּ אֵלָיו׃

The mizbeach was torn apart, and the ashes poured out.
וְהַמִּזְבֵּחַ נִקְרָע וַיִּשָּׁפֵךְ הַדֶּשֶׁן מִן הַמִּזְבֵּחַ כַּמּוֹפֵת אֲשֶׁר נָתַן אִישׁ הָאֱלֹקִים בִּדְבַר ה'׃
