אָדָ֣ם עָ֭רוּם כֹּ֣סֶה דָּ֑עַת וְלֵ֥ב כְּ֝סִילִ֗ים יִקְרָ֥א אִוֶּֽלֶת׃
Orang yang cerdik menyembunyikan pengetahuannya, tetapi hati orang-orang bebal menyerukan kebodohan.
Ibn Ezra
you became covered [Hebrew: kas̀ita] Some say that the word is related to “he has covered [Hebrew: khissah] his face with his fat” [Job 15: 27], since the verb also appears in the qal form [e.g., Proverbs 12: 23]. Others say that it is from “I wandered like a lamb [Hebrew: kes̀eh] gone astray” [Psalms 119: 176] — except that there is no verbal form that uses an auxiliary kaf. The correct interpretation, in my opinion, is that this word has no cognate, and that its meaning is similar to “you kicked”.
