'Opinions' in the Bible

Elijah approached all the people and said, “How long will you hesitate between two opinions? If the Lord is God, follow Him; but if Baal, follow him.” But the people [of Israel] did not answer him [so much as] a word.

A [closed-minded] fool does not delight in understanding,But only in revealing his personal opinions [unwittingly displaying his self-indulgence and his stupidity].
