Ezekiel 21:5-7

5That all flesh may know that I the Lord have drawn forth my sword out of his sheath: it shall not return any more.

6Sigh therefore, thou son of man, with the breaking of thy loins; and with bitterness sigh before their eyes.

7And it shall be, when they say unto thee, Wherefore sighest thou? that thou shalt answer, For the tidings; because it cometh: and every heart shall melt, and all hands shall be feeble, and every spirit shall faint, and all knees shall be weak as water: behold, it cometh, and shall be brought to pass, saith the Lord God.1
