'Sharp' in the Bible

He had seven stars in his right hand. Out of his mouth proceeded a sharp two-edged sword. His face was like the sun shining at its brightest.

"To the angel of the assembly in Pergamum write: "He who has the sharp two-edged sword says these things:

I looked, and behold, a white cloud; and on the cloud one sitting like a son of man, having on his head a golden crown, and in his hand a sharp sickle.

Another angel came out from the temple which is in heaven. He also had a sharp sickle.

Another angel came out from the altar, he who has power over fire, and he called with a great voice to him who had the sharp sickle, saying, "Send forth your sharp sickle, and gather the clusters of the vine of the earth, for the earth's grapes are fully ripe!"

Out of his mouth proceeds a sharp, double-edged sword, that with it he should strike the nations. He will rule them with an iron rod. He treads the winepress of the fierceness of the wrath of God, the Almighty.
