Jezekiel 21:5

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

Jezekiel 21:5 In-Context

3 and thou shalt say to the land of Israel, Thus saith the Lord; Behold, I am against thee, and I will draw forth my sword out of its sheath, and I will destroy out of thee the transgressor and unrighteous.
4 Because I will destroy out of thee the unrighteous and the transgressor, so shall my sword come forth out of its sheath against all flesh from the south to the north:
5 and all flesh shall know that I the Lord have drawn forth my sword out of its sheath: it shall not return any more.
6 And thou, son of man, groan with the breaking of thy loins; thou shalt even groan heavily in their sight.
7 And it shall come to pass, if they shall say to thee, Wherefore dost thou groan? that thou shalt say, For the report; because it comes: and every heart shall break, and all hands shall become feeble, and all flesh and every spirit shall faint, and all thighs shall be defiled with moisture: behold, it comes, saith the Lord.
