אהלה. אהלה כְּתִיב, רֶמֶז לְי' שְׁבָטִים שֶׁנִּקְרְאוּ עַל שֵׁם שׁוֹמְרוֹן, שֶׁנִּקְרֵאת אָהֳלָה שֶׁגָּלוּ עַל עִסְקֵי הַיַּיִן שֶׁנֶּאֱמַר הַשֹּׁתִים בְּמִזְרְקֵי יַיִן (עמוס ו'):
אהלה HIS TENT — This word is written אהלה (with ה at end instead of ו) so that it may be regarded as an allusion to the ten tribes who were spoken of as Samaria which was called “אהלה” Ohala and who were exiled because of indulgence in wine, at it is said (Amos 6:6) ‘‘that drink wine in bowls”.
