'Edge of the Sword' in the Bible

And the Sabeans fell on and took them away. Yea, they have killed the servants with the edge of the sword. And I only have escaped alone to tell you.

While he was still speaking, there also came another and said, The Chaldeans made out three bands and swooped down upon the camels, and have carried them away, yea, and have killed the servants with the edge of the sword. And I only have escaped alone to tell you.
