Let both grow together - that is, in the visible Church.
until the harvest - till the one have ripened for full salvation, the other for destruction. (See on Mat 13:39).
and in the time of harvest I will say to the reapers - (See on Mat 13:39).
Gather ye together first the tares, and bind them in bundles to burn them - “in the fire” (Mat 13:40).
but gather the wheat into my barn - Christ, as the Judge, will separate the two classes (as in Mat 25:32). It will be observed that the tares are burned before the wheat is housed; in the exposition of the parable (Mat 13:41, Mat 13:43) the same order is observed: and the same in Mat 25:46 - as if, in some literal sense, “with thine eyes shalt thou behold and see the reward of the wicked” (Psa 91:8).
