'Foolish' in the Bible

'And every one who is hearing of me these words, and is not doing them, shall be likened to a foolish man who built his house upon the sand;

and five of them were prudent, and five foolish;

they who were foolish having taken their lamps, did not take with themselves oil;

and the foolish said to the prudent, Give us of your oil, because our lamps are going out;

an instructor of foolish ones, a teacher of babes, having the form of the knowledge and of the truth in the law.

where is the wise? where the scribe? where a disputer of this age? did not God make foolish the wisdom of this world?

but the foolish things of the world did God choose, that the wise He may put to shame; and the weak things of the world did God choose that He may put to shame the strong;

also filthiness, and foolish talking, or jesting, -- the things not fit -- but rather thanksgiving;

and those wishing to be rich, do fall into temptation and a snare, and many desires, foolish and hurtful, that sink men into ruin and destruction,

and the foolish and uninstructed questions be avoiding, having known that they beget strife,

and foolish questions, and genealogies, and contentions, and strivings about law, stand away from -- for they are unprofitable and vain.

having known that, not with corruptible things -- silver or gold -- were ye redeemed from your foolish behaviour delivered by fathers,

because, so is the will of God, doing good, to put to silence the ignorance of the foolish men;
