Surely I am too stupid to be a man. I have not the understanding of a man. I have not learned wisdom, nor have I knowledge of the Holy One. Who has ascended to heaven and come down? Who have gathered the wind in his fists? Who has wrapped up the waters in a garment? Who has established all the ends of the earth? What is his name, and what is his son's name? Surely you know!
(Proverbs 20:2-4)
"For my people are foolish; they know me not; they are stupid children; they have no understanding. They are 'wise'--in doing evil! But how to do good they know not." (Jeremiah 4:22)
"Every man is stupid and without knowledge; every goldsmith is put to shame by his idols, for his idols are false, and there is no breath in them. They are worthless, a work of delusion; at the time of their punishment they shall perish." (Jeremiah 51:17-18)
