Jezekiel 21:9 In-Context

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.
8 And the word of the Lord came to me, saying,
9 Son of man, prophesy, and thou shalt say, Thus saith the Lord; Say, Sword, sword, be sharpened and rage,
10 that thou mayest slay victims; be sharpened that thou mayest be bright, ready for slaughter, slay, set at nought, despise every tree.
11 And he made it ready for his hand to hold: the sword is sharpened, it is ready to put into the hand of the slayer.
