Ezekiel 24:22-23

You will do as I [Ezekiel] have done; you shall not cover your mustache nor eat the bread of [mourning brought to you by other] men. Your turbans will be on your heads and your sandals on your feet. You will not mourn or weep, but you will rot away in your sins and you will groan to one another. [Lev 26:39]
