Doctrine and Covenants 86:5-7
5 Behold, verily I say unto you, the angels are crying unto the Lord day and night, who are ready and waiting to be sent forth to reap down the fields;
6 But the Lord saith unto them, pluck not up the tares while the blade is yet tender (for verily your faith is weak), lest you destroy the wheat also.
7 Therefore, let the wheat and the tares grow together until the harvest is fully ripe; then ye shall first gather out the wheat from among the tares, and after the gathering of the wheat, behold and lo, the tares are bound in bundles, and the field remaineth to be burned.
