“The field is the world.
The good seeds
Are the children
Of the kingdom.
The weeds
Are the children
Of the evil one.”
ὁ δὲ ἀγρός ἐστιν ὁ κόσμος· τὸ δὲ καλὸν σπέρμα, οὗτοί εἰσιν οἱ υἱοὶ τῆς βασιλείας· τὰ δὲ ζιζάνιά εἰσιν οἱ υἱοὶ τοῦ πονηροῦ,
Only Matthew has this explanation about the parable of the weeds that was earlier in this chapter, 13:24-30. Jesus, via Matthew, went into great detail about this earlier parable, as he explained the field, the good seed, and the weeds. The field was the world (ὁ δὲ ἀγρός ἐστιν ὁ κόσμος). The good seeds were the sons of the kingdom (τὸ δὲ καλὸν σπέρμα, οὗτοί εἰσιν οἱ υἱοὶ τῆς βασιλείας). The weeds were the sons of the evil one (τὰ δὲ ζιζάνιά εἰσιν οἱ υἱοὶ τοῦ πονηροῦ). This is the classic battle of good and evil in the world with the sons of the kingdom against the sons of the evil one.
