"For, behold, I will command, and I will sift the house of Israel among all the nations, as grain is sifted in a sieve, yet not the least kernel will fall on the earth.
"Not the least kernel shall fall to earth ..." This means that no Israelite, or any other person on earth, who truly loves and seeks to do the will of God will be cut off, regardless of the evil nature of any kingdom, or group of people, with whom he may be environmentally associated.  God knows what he is doing.
