אבי ישב אהל ומקנה. הוּא הָיָה הָרִאשׁוֹן לְרוֹעֵי בְהֵמוֹת בַּמִּדְבָּרוֹת, יוֹשֵׁב אֹהָלִים חֹדֶשׁ כָּאן וְחֹדֶשׁ כָּאן בִּשְׁבִיל מִרְעֵה צֹאנוֹ, וּכְשֶׁכָּלֶה הַמִּרְעֶה בְּמָקוֹם זֶה הוֹלֵךְ וְתוֹקֵעַ אָהֳלוֹ בְּמָקוֹם אַחֵר. וּמִדְרַשׁ אַגָּדָה בּוֹנֶה בָתִּים לַעֲ"זָ, כְּמָה דְּאַתְּ אָמַר סֵמֶל הַקִּנְאָה הַמַּקְנֶה (יחזקאל ח'), וְכֵן אָחִיו תּוֹפֵשׂ כִּנּוֹר וְעוּגָב לְזַמֵּר לַעֲ"זָ:

אבי יושב אהל ומקנה THE FATHER OF SUCH AS ABIDE IN TENTS AND OF SUCH THAT HAVE CATTLE — He was the first of those who pastured cattle, and he dwelt in tents, a month here and a month there, on account of the pasture necessary for his sheep; for when the grass was finished in one place he went away and pitched his tent in another place. There is a Midrashic statement (Genesis Rabbah 23:3) that he built temples for idol worship, (for ומקנה may be read ומקנה –– provoking jealousy), just as you say, (Ezekiel 8:3) "the image of jealousy which provoketh God to jealousy" (המקנה); similarly his brother handled the harp and guitar to make music for idol worship.
