KJV:
I have set the point of the sword against all their gates, that their heart may faint, and their ruins be multiplied: ah! it is made bright, it is wrapped up for the slaughter.
NASB:
that their hearts may melt, and many fall at all their gates. I have given the glittering sword. Ah! It is made for striking like lightning, it is wrapped up in readiness for slaughter.
