Proverbs 27:4

Envy is worse than both of them, partly, because it is more unjust and unreasonable, as not caused by any provocation, as wrath and anger are, but only proceeding from a malignity of mind, whereby a man is grieved for another man's happiness, in which he should rejoice; partly, because it is more deeply rooted and implacable, whereas the other passions are commonly allayed; and partly, because it is more secret and undiscernible, and therefore the mischievous effects of it are hardly avoidable; whereas wrath and anger discover themselves, and so forewarn and forearm a man against the danger.
