'Reaping' in the Bible

"But, next, the man who had the one talent in his keeping came and said, "'Sir, I knew you to be a severe man, reaping where you had not sown and garnering what you had not winnowed.

"'By your own words,' he replied, 'I will judge you, you bad servant. You knew me to be a severe man, taking up what I did not lay down, and reaping what I did not sow:

And another, an angel, came out of the sanctuary, calling in a loud voice to Him who sat on the cloud, and saying, "Use your sickle and reap the harvest, for the hour for reaping it has come: the harvest of the earth is over-ripe."
