Sharpened for the slaughter, polished to flash like lightning! "Shall we rejoice in the scepter of my royal son? The sword despises every such stick."
NIV
It [the sword of Babylon] is sharpened that it may make a slaughter, polished that it may flash and glitter like lightning! Shall we then rejoice and make mirth [when such a calamity is impending]? But the rod or scepter of My son [Judah] rejects and views with contempt every tree [that is, since God's promise long ago to Judah is certain, he believes Judah's scepter must remain no matter what power arises against it]! [Gen. 49:9, 10; II Sam. 7:23.]AMP
It is sharpened to make a sore slaughter; it is furbished that it may glitter: should we then make mirth? it contemneth the rod of my son, as every tree.
