Ezekiel 21:5
That all flesh may know that I the LORD have drawn forth my sword out of his sheath: it shall not return any more.
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.
