2 Bible Verses about Foolishness

And every man who is hearing these sayings of mine, and doth not practise them, he will resemble the foolish man, who built his house upon the sand: and the rain descended, and the rivers rushed, and the winds blew, and set against that house, and it fell; and the fall of it was great.
