39. The enemy that sowed them is the devil--emphatically "His enemy" (Mt 13:25). (See Ge 3:15; 1Jo 3:8). By "tares" is meant, not what in our husbandry is so called, but some noxious plant, probably darnel. "The tares are the children of the wicked one"; and by their being sown "among the wheat" is meant their being deposited within the territory of the visible Church. As they resemble the children of the kingdom, so they are produced, it seems, by a similar process of "sowing"--the seeds of evil being scattered and lodging in the soil of those hearts upon which falls the seed of the world. The enemy, after sowing his "tares," "went his way"--his dark work soon done, but taking time to develop its true character.
      The harvest is the end of the world--the period of Christ's second coming, and of the judicial separation of the righteous and the wicked. Till then, no attempt is to be made to effect such separation. But to stretch this so far as to justify allowing openly scandalous persons to remain in the communion of the Church, is to wrest the teaching of this parable to other than its proper design, and go in the teeth of apostolic injunctions (1Co 5:1-13).
      And the reapers are the angels--But whose angels are they? "The Son of man shall send forth His angels" (Mt 13:41). Compare 1Pe 3:22, "Who is gone into heaven, and is on the right hand of God; angels and authorities and powers being made subject unto him."
