'Sickle' in the Bible

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

And another angel came out from the temple, crying with a great voice to him that sat on the cloud, Send forth thy sickle, and reap: for the hour to reap is come; for the harvest of the earth is ripe.

And he that sat on the cloud cast his sickle upon the earth; and the earth was reaped.

Another angel came out from the temple which is in heaven, he also having a sharp sickle.

And another angel came out from the altar, he that hath power over fire; and he called with a great voice to him that had the sharp sickle, saying, Send forth thy sharp sickle, and gather the clusters of the vine of the earth; for her grapes are fully ripe.

And the angel cast his sickle into the earth, and gathered the vintage of the earth, and cast it into the winepress, the great winepress , of the wrath of God.
