Matthew 13:27-30

27 And the servants of the good man of the house coming said to him. Sir, didst thou not sow good seed in thy field? Whence then hath it cockle?

28 And he said to them: An enemy hath done this. And the servants said to him: Wilt thou that we go and gather it up?

29 And he said: No, lest perhaps gathering up the cockle, you root up the wheat also together with it.

30 Suffer both to grow until the harvest, and in the time of the harvest I will say to the reapers: Gather up first the cockle, and bind it into bundles to burn, but the wheat gather ye into my barn.
