(Bamidbar 25:12) "Therefore, say: Behold, I give to him My covenant to be to him a covenant of peace": … whereby we are apprised that there descended from him twelve high-priests in the first Temple, whereby in the second Temple there were eighty high-priests, whose lives began to be shortened because they sold the high-priesthood for money. Once, a man sent by his son two urns of silver rimmed with silver (as a bribe), and another, two urns of gold rimmed with gold" — whereupon they said "The foal has outweighed the menorah."
