2 Bible Verses about Foolishness

"And every one who hears these words of Mine, and does them not, shall be likened to a foolish man, who, indeed, built his house upon the sand: and the rain descended, and the streams came, and the winds blew and beat upon that house; and it fell; and great was its fall."
