'Foolish' in the Bible

“For My people are foolish,They know Me not;They are stupid childrenAnd have no understanding.They are shrewd to do evil,But to do good they do not know.”

Then I said, “They are only the poor,They are foolish;For they do not know the way of the LordOr the ordinance of their God.

‘Now hear this, O foolish and senseless people,Who have eyes but do not see;Who have ears but do not hear.

But they are altogether stupid and foolishIn their discipline of delusion—their idol is wood!
