Darby
10 It is sharpened for sore slaughter, it is furbished that it may glitter. Shall we then make mirth, [saying,] The sceptre of my son contemneth all wood?
KJV
10 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.
