Context
30 Let both grow together until the harvest, and in the harvest time I will tell the reapers, “First, gather up the darnel weeds, and bind them in bundles to burn them; but gather the wheat into my barn.”’”
31 He set another parable before them, saying, “The Kingdom of Heaven is like a grain of mustard seed which a man took, and sowed in his field,
32 which indeed is smaller than all seeds. But when it is grown, it is greater than the herbs and becomes a tree, so that the birds of the air come and lodge in its branches.”
