'Foolishness' in the Bible

Therefore the Lord does not take pleasure in their young men,Nor does He have pity on their orphans or their widows;For every one of them is godless and an evildoer,And every mouth is speaking foolishness.In spite of all this, His anger does not turn awayAnd His hand is still stretched out.

For a fool speaks foolishnessand his mind plots iniquity.He lives in a godless wayand speaks falsely about the Lord.He leaves the hungry emptyand deprives the thirsty of drink.

who destroys the omens of the false prophetsand makes fools of diviners;who confounds the wiseand makes their knowledge foolishness;
