It is helpful to know that the weed named here is a particular kind (zizania) known for its confusing resemblance to wheat in the early stages of growth. That helps us to understand why pulling up the weeds might uproot the wheat along with them.
John Kavanaugh, SJ
In all the happenstance of history and space, the gospel tells us that the good lasts. It is worth the vast expenditure of matter and energy to gain the good.
