Ecclesiastes 10:1-3

Wycliffe Bible

10 Flies that die (in it), lose the sweetness of [the] ointment. A little folly at some time is more precious than wisdom and glory. (Flies that die in an ointment can destroy its sweetness. And so a little foolishness can sometimes destroy wisdom and glory.)

² The heart of a wise man is in his right side; and the heart of a fool is in his left side. (The heart of a wise person is in the right; and the heart of a fool is in the wrong.)

³ But also a fool going in the way, when he is unwise, guesseth all men fools. (And a fool, going on the way, since he is unwise, thinketh that all the other people be fools.)
