'Sharp' in the Bible

He held seven stars in his right hand, and a sharp double-edged sword extended out of his mouth. His face shone like the sun shining at full strength.

"To the angel of the church in Pergamum write the following: "This is the solemn pronouncement of the one who has the sharp double-edged sword:

Then I looked, and a white cloud appeared, and seated on the cloud was one like a son of man! He had a golden crown on his head and a sharp sickle in his hand.

Then another angel came out of the temple in heaven, and he too had a sharp sickle.

Another angel, who was in charge of the fire, came from the altar and called in a loud voice to the angel who had the sharp sickle, "Use your sharp sickle and gather the clusters of grapes off the vine of the earth, because its grapes are now ripe."

From his mouth extends a sharp sword, so that with it he can strike the nations. He will rule them with an iron rod, and he stomps the winepress of the furious wrath of God, the All-Powerful.
