A noun denoting a knife, appearing in Proverbs 23:2 in wisdom instruction about dining with rulers. The word is likely a loanword from Aramaic (סַכִּינָא), which borrowed it into Arabic (سِكِّينٌ). This linguistic journey reflects ancient Near Eastern trade and cultural exchange. In late biblical Hebrew and rabbinic literature, the term became standard for knife. Proverbs uses it metaphorically: put a knife to your throat if you're given to appetite—shocking imagery warning against gluttony in the presence of authority. The knife represents self-control, even violent restraint, to avoid shameful excess.
