אָח Howler (o'ach)
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, in Yeshayahu 13:21 — the ochim that fill the houses of fallen Bavel. Traditionally a howling desert creature, perhaps the eagle-owl; the identification is discussed. The bare letters are everywhere else 'brother.'
וְרָבְצוּ־שָׁם צִיִּים וּמָלְאוּ בָתֵּיהֶם אֹחִים וְשָׁכְנוּ שָׁם בְּנוֹת יַֽעֲנָה וּשְׂעִירִים יְרַקְּדוּ־שָֽׁם
But wild-cats shall lie there; And their houses shall be full of ferrets; And ostriches shall dwell there, And satyrs shall dance there.

The bare letters אח stand 15 times in the corpus, which is a different question and often a different number: the same letters can spell a name or another word entirely, and the creature written with a particle attached is a spelling that search never returns. It is here, as itself.
