Luke 13:20

And again he said
That is, Jesus, as the Syriac and Persic versions express it; besides the parable of the grain of mustard seed, that also of the leaven hid in three measures of meal:

whereunto shall I liken the kingdom of God;
either the Gospel of the kingdom, and the mysteries of it; or the church, which is Christ's kingdom; or the grace of God in the heart, which makes meet for the kingdom of glory; the first seems rather to be intended; (See Gill on Matthew 13:33).
