Ezekiel 21:8

5 And all flesh will see that I the Lord have taken my sword out of its cover: and it will never go back.

6 Make sounds of grief, son of man; with body bent and a bitter heart make sounds of grief before their eyes.

7 And when they say to you, Why are you making sounds of grief? then say, Because of the news, for it is coming: and every heart will become soft, and all hands will be feeble, and every spirit will be burning low, and all knees will be turned to water: see, it is coming and it will be done, says the Lord.

8 And the word of the Lord came to me, saying,

9 Son of man, say as a prophet, These are the words of the Lord: Say, A sword, a sword which has been made sharp and polished:

10 It has been made sharp to give death; it is polished so that it may be like a thunder-flame:...

11 And I have given it to the polisher so that it may be taken in the hand: he has made the sword sharp, he has had it polished, to put it into the hand of him who gives death.
