In chapter 21 the sword, a common symbol of divine [[judgment]], is about to be unsheathed against [[Jerusalem]] and Ammon. It is seen sharpened, indicating [[judgment]] is imminent. Verses 18-32 are actually referring to the s[[Word]] of Nebuchadnezzar. It was his s[[Word]] that would be used as a means of [[God]]'s [[judgment]]. The phrase "until he come whose right it is" refers to the overturning of Zedekiah's house, the end of [[David]]'s kingdom until the coming of the [[Messiah]] .
