'Edge' in the Bible

Then the devil takes him to the holy city, and sets him upon the edge of the temple,

And he led him to Jerusalem, and set him on the edge of the temple, and said to him, If thou be Son of God, cast thyself down hence;

And they shall fall by the edge of the sword, and be led captive into all the nations; and Jerusalem shall be trodden down of the nations until the times of the nations be fulfilled.

quenched the power of fire, escaped the edge of the sword, became strong out of weakness, became mighty in war, made the armies of strangers give way.
