'Foolish' in the Bible

And everyone who hears these words of Mine and does not do them, will be like a foolish (stupid) man who built his house on the sand.

Five of them were foolish [thoughtless, silly, and careless], and five were wise [far-sighted, practical, and sensible].

For when the foolish took their lamps, they did not take any [extra] oil with them,

But the foolish virgins said to the wise, ‘Give us some of your oil, because our lamps are going out.’
