He putteth in the sickle. — From one point of view, here again, the harvest is the end of the world (Matthew 13:39), and the putting in the sickle is the coming of Christ to judge. (Comp. the use of the same image in Revelation 14:14-18.) From the other, the harvest is the end of each man’s life, and the sickle is in the hands of the Angel of Death.
