'Sharp' in the Bible

And a sharp disagreement took place, so that they separated from one another. And Barnabas took along Mark [and] sailed away to Cyprus,

and [he] had in his right hand seven stars, and a sharp double-edged sword coming out of his mouth, and his face [was] like the sun shining in its strength.

"And to the angel of the church in Pergamum write: "This is what the one who has the sharp double-edged sword says:

And I looked, and behold, a white cloud, and on the cloud was seated [one] like a son of man, having on his head a golden crown, and in his hand a sharp sickle.

And another angel came out of the temple [that is] in heaven; he also had a sharp sickle.

And another angel who had authority over the fire [went out] from the altar, and he called out with a loud voice to the one who had the sharp sickle, saying, "Send out your sharp sickle and harvest the clusters of grapes from the vine of the earth, because its grapes are at their prime!"

And out of his mouth came a sharp sword, so that with it he could strike the nations. And he will shepherd them with an iron rod, and he stomps the winepress of the wine of the furious wrath of God, the All-Powerful.
