Ezekiel 24:20-24

20Then I answered them, “The word of the Lord came to me, saying,

21‘Speak to the house of Israel, “Thus says the Lord God, ‘Behold, I will profane My sanctuary, the pride of your strength, the desire of your eyes, and the delight of your soul; and your sons and your daughters whom you have left behind [in Jerusalem] will fall by the sword.

22You 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.

23Your 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.

24So Ezekiel will be a sign to you; in accordance with all that he has done you will do. And when this [destruction of the temple] comes, then you will know [without any doubt] that I am the Lord God.’ ”
