וְשַׁחֲטָ֥ה שֵׂטִ֖ים הֶעְמִ֑יקוּ וַאֲנִ֖י מוּסָ֥ר לְכֻלָּֽם׃
Os revoltosos se aprofundaram na corrupção; mas eu os castigarei a todos eles.

Their tongue is a deadly arrow Heb. שחוט, drawn. Comp. (I Kings 10:16) “malleable gold” (שחוט). Also, (Hos. 5:2) “And the extent of their turning away (ושחטה),” (tirer in French), pulling. Another explanation is that it is actually an expression of slaughter (tranchant in French, cutting). In this manner Menahem classified it (Machbereth Menahem p. 172), and in this manner Jonathan rendered it: כּגיר די מחרף, like a sharpened arrow.
