Mark.4.29  But when the grain is ripe, at once he puts in the sickle, because the harvest has come."
Rev.14.15  And another angel came out of the temple, calling with a loud voice to him who sat upon the cloud, "Put in your sickle, and reap, for the hour to reap has come, for the harvest of the earth is fully ripe."
Rev.14.18  Then another angel came out from the altar, the angel who has power over fire, and he called with a loud voice to him who had the sharp sickle, "Put in your sickle, and gather the clusters of the vine of the earth, for its grapes are ripe."
