To live off the fat of the land 意為「錦衣玉食；過著養尊處優的生活」。這個成語首次被用在 1611 年翻譯和出版的《欽定版聖經》(Authorized Version) － 又稱《詹姆士王譯本》(King James Version) 或《詹姆士王聖經》(King James Bible) －《創世紀》(Genesis) 第 45 章第 18 節中：”And take your father and your households, and come unto me: and I will give you the good of the land of Egypt, and ye shall eat the fat of the land.” (將你們的父親和你們的眷屬都帶到我這裡來，我要把埃及土地的美物賜給你們，你們也要吃這土地肥美的物產)。這個成語有時亦被說成或寫成 to live on the fat of the land。
例句：
