ציטירנדיקער פּירוש אויף ירמיהו 35:7

ואהלים, an indication that he had so many chattels that it required many tents to accommodate them. The word אהלים is spelled with the vowel cholem on the letter aleph, as it is also in Samuel I 4,10 and in Deut. 33,18 ויששכר באהליך According to the regular rules of grammar, the letter א in אהל should have the vowel chataf kametz as is the case in Jeremiah 35,7 and in Judges 8,11. Perhaps when the letter א has the vowel cholem, this is an indication that the noun is in a different declination, a declination known as גוזל תולע. [I confess not to know what this is. Ed.]
