רִֽ֭יבְךָ רִ֣יב אֶת־רֵעֶ֑ךָ וְס֖וֹד אַחֵ֣ר אַל־תְּגָֽל׃
너는 이웃과 다투거든 변론만 하고 남의 은밀한 일은 누설하지 말라
Ibn Ezra
a shameful perversion [Hebrew: ḥesed] from “lest the hearer put you to shame” [Proverbs 25:10]. The word denotes an egregious sexual crime.
Rashi
And do not conceal Heb. וְאַל תְּכַס, like וְאַל תְּכַסֶה, similar to (Prov. 25:9): “...but do not divulge (תְּגָל) another’s secret,” like תְּגַלֶה.
