ברבר Fatted fowl (barburim)
Every verse in which this word stands — 1 place, in canonical order, first appearance to last. These are the places the lexicon carries under this word's own entry, counting every form the text writes it in, which is the number on the list.
Once, on Shlomo's daily table — 'and fatted barburim.' Geese, swans, capons, guinea-fowl: the renderings multiply and the identification is discussed. The corpus writes it only with a particle attached.
עֲשָׂרָה בָקָר בְּרִאִים וְעֶשְׂרִים בָּקָר רְעִי וּמֵאָה צֹאן לְבַד מֵֽאַיָּל וּצְבִי וְיַחְמוּר וּבַרְבֻּרִים אֲבוּסִֽים
ten fat oxen, and twenty oxen out of the pastures, and a hundred sheep, beside harts, and gazelles, and roebucks, and fatted fowl.
