הֲלֹא־אֹ֭זֶן מִלִּ֣ין תִּבְחָ֑ן וְ֝חֵ֗ךְ אֹ֣כֶל יִטְעַם־לֽוֹ׃
דאַרף ניט דאָס אױער פּרוּװן װערטער, אַזױ װי דער גומען פֿאַרזוכט זײַן שפּײַז?
Rashi
Does not the ear discern words So why did the listeners not know this, as the palate tastes to eat?
Malbim
Job rejects Zophar's assertion that our observations and sensory perceptions do not reflect the true essence of things. On the contrary, the wisdom and understanding we amass during our lives are true, for their source is God. By virtue of His omniscience, He is the font of all knowledge. However, though man's knowledge is real, his free-will is an illusion, for God's foreknowledge predetermines everything.
