'Blade' in the Bible

And I saw a white cloud, and on the cloud I saw one seated, like a son of man, having on his head a crown of gold, and in his hand a sharp curved blade.

And another angel came out from the house of God, crying with a loud voice to him who was seated on the cloud, Put in your blade, and let the grain be cut: because the hour for cutting it is come; for the grain of the earth is over-ready.

And he who was seated on the cloud sent in his blade on the earth; and the grain of the earth was cut.

And another angel came out from the house of God which is in heaven, having a sharp curved blade.

And another angel came out from the altar, who has power over fire; and he gave a loud cry to him who had the sharp curved blade, saying, Put in your sharp blade, and let the grapes of the vine of the earth be cut; for her grapes are fully ready.

And the angel sent his blade into the earth, and the vine of the earth was cut, and he put it into the great wine-crusher of the wrath of God.
