שְׂאִֽי־עֵינַ֨יִךְ עַל־שְׁפָיִ֜ם וּרְאִ֗י אֵיפֹה֙ לֹ֣א שגלת [שֻׁכַּ֔בְתְּ] עַל־דְּרָכִים֙ יָשַׁ֣בְתְּ לָהֶ֔ם כַּעֲרָבִ֖י בַּמִּדְבָּ֑ר וַתַּחֲנִ֣יפִי אֶ֔רֶץ בִּזְנוּתַ֖יִךְ וּבְרָעָתֵֽךְ׃
你要舉目觀看光禿的高處,看看你在哪裡沒有與人苟合?你坐在路旁等候他們,好像阿拉伯人在曠野埋伏一樣;你用你的淫行和惡事玷污了這地。
Rashi
like an Arab A tent dweller, who is always found outside in the deserts, and because of this, he is called ערבי since he dwells in the ערבה, the plain.
