Eclesiastés 10

Moreover, as a foolish man is walking along the way, even though he himself is unwise, he considers everyone to be foolish.

Y aun mientras va el necio por el camino, fáltale su cordura, y dice á todos, que es necio.

Yea also, when he that is a fool walketh by the way, his wisdom faileth him, and he saith to every one that he is a fool.

Yes also when the fool walks by the way, his understanding fails him, and he says to everyone that he is a fool.
