阅读下面的文言文,完成下列小题。

    侯蒙,字元功,密州高密人。未冠,有俊声,急义好施,或一日挥千金。进士及第,调宝鸡尉,知柏乡县。民讼皆决于庭,受罚者不怨。转运使黄湜闻其名,将推毂之,召诣行台白事,蒙以越境不肯往。湜怒,他日行县,阅理文书,欲翻致其罪;既而无一疵可指,始以宾礼见,曰:“君真能吏也。”率诸使者合荐之。

    西将高永年死于羌,帝怒,亲书五路将帅刘仲武等十八人姓名,敕蒙往秦州逮治。至秦,仲武等囚服听命,蒙晓之曰:“君辈皆侯伯,无庸以狱吏辱君,第以实对。”案未上,又拜御史中丞。蒙奏言:“汉武帝杀王恢①,不如秦缪公赦孟明;子玉②缢而晋侯喜,孔明亡而蜀国轻。今羌杀吾一都护,而使十八将由之而死,是自艾其支体也。欲身不病,得乎?”帝悟,释不问。

    迁刑部尚书,改户部。一日,帝从容问:“蔡京何如人?”对曰:“使京能正其心术,虽古贤相何以加。”帝颔首,且使密伺京所为。京闻而衔之。

    大钱法敝,朝廷议改十为三,主藏吏来告曰:“诸府悉辇大钱市物于肆,皆疑法当变。”蒙曰:“吾府之积若干?”曰:“八千缗。”蒙叱曰:“安有更革而吾不知!”明日,制下。又尝有凡事蒙独受旨,京不知也;京侦得之,白于帝,帝曰:“侯蒙亦如是邪?”罢知亳州。

    宋江寇京东,蒙上书言:“江以三十六人横行齐魏官军数万无敢抗者其才必过人今青溪盗起不若赦江使讨方腊以自赎。”帝曰:“蒙居外不忘君,忠臣也。”命知东平府,未赴而卒,年六十八。
