Ezekiel 21:5

5 and all flesh shall know that I the Lord have drawn my sword out of its sheath; it shall not be sheathed again.

Ezekiel 21:5 Meaning and Commentary

Ezekiel 21:5

That all flesh may know that I the Lord have drawn forth my
sword out of his sheath
The same with kindling a fire in Judea, (See Gill on Ezekiel 20:48): it shall not return any more;
that is, into its sheath, until it has done all its work; meaning that the Chaldean army should not return to their own land until they had executed the whole will of God upon the Jews; this is the fire that should not be quenched, ( Ezekiel 20:48 ) and here ends the explanation of the said prophecy.

Ezekiel 21:5 In-Context

3 and say to the land of Israel, Thus says the Lord: I am coming against you, and will draw my sword out of its sheath, and will cut off from you both righteous and wicked.

4 Because I will cut off from you both righteous and wicked, therefore my sword shall go out of its sheath against all flesh from south to north;

5 and all flesh shall know that I the Lord have drawn my sword out of its sheath; it shall not be sheathed again.

6 Moan therefore, mortal; moan with breaking heart and bitter grief before their eyes.

7 And when they say to you, "Why do you moan?" you shall say, "Because of the news that has come. Every heart will melt and all hands will be feeble, every spirit will faint and all knees will turn to water. See, it comes and it will be fulfilled," says the Lord God.
