סלעם Sol'am
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 Vayikra 11:22, second of the four permitted kinds. Traditionally the bald locust; the identification is discussed — the Gemara itself works through the signs of these kinds.
אֶת־אֵלֶּה מֵהֶם תֹּאכֵלוּ אֶת־הָֽאַרְבֶּה לְמִינוֹ וְאֶת־הַסָּלְעָם לְמִינֵהוּ וְאֶת־הַחַרְגֹּל לְמִינֵהוּ וְאֶת־הֶחָגָב לְמִינֵֽהוּ
even these of them ye may eat: the locust after its kinds, and the bald locust after its kinds, and the cricket after its kinds, and the grasshopper after its kinds.
