'Edge' in the Bible

and they of Sheba fell upon them and took them, and the servants have they smitten with the edge of the sword; and I only am escaped, alone, to tell thee.

While he was yet speaking, there came another and said, The Chaldeans made three bands, and fell upon the camels and took them, and the servants have they smitten with the edge of the sword; and I only am escaped, alone, to tell thee.
