John Lightfoot on Matthew 13:25

[Tares.] Zunin, in Talmudic language. Wheat and 'Zunin' are not seeds of different kinds. Where the Gloss is this; "Is a kind of wheat, which is changed in the earth, both as to its form, and to its nature." By the best Lexicographers it is rendered zizania, in Latin.

So that that field, in this parable, was sown by the lord with good wheat; by the enemy, with bad and degenerate wheat; but all of it was sown with wheat, one or the other. These words do not so barely mean good and bad men, as good and bad Christians; both distinguished from other men, namely, from heathens, as wheat is distinguished from other seeds: but they are distinguished also among themselves, as good wheat is distinguished from that which is degenerate. So chapter 25, all those ten women, expecting the bridegroom, are virgins; but are distinguished into wise and foolish.
