Discovery BoxLuke 8:8 
Context8:8 But 1 other seed fell on good soil and grew, 2 and it produced a hundred times as much grain.” 3 As he said this, 4 he called out, “The one who has ears to hear had better listen!” 5
Luke 13:19
Context13:19 It is like a mustard seed 6 that a man took and sowed 7 in his garden. It 8 grew and became a tree, 9 and the wild birds 10 nested in its branches.” 11
1 tn Here καί (kai) has been translated as “but” to indicate the contrast present in the final stage of the parable.
2 tn Grk “when it grew, after it grew.”
3 sn Unlike the parallel accounts in Matt 13:8 and Mark 4:8, there is no distinction in yield in this version of the parable.
4 tn Grk “said these things.”
5 tn The translation “had better listen!” captures the force of the third person imperative more effectively than the traditional “let him hear,” which sounds more like a permissive than an imperative to the modern English reader. This was Jesus’ common expression to listen and heed carefully (cf. Matt 11:15; 13:9, 43; Mark 4:9, 23; Luke 14:35).
6 sn The mustard seed was noted for its tiny size.
7 tn Grk “threw.”
8 tn Grk “garden, and it.” Here καί (kai) has not been translated because of differences between Greek and English style. Because of the length and complexity of the Greek sentence, a new sentence was started here in the translation.
9 sn Calling the mustard plant a tree is rhetorical hyperbole, since technically it is not one. This plant could be one of two types of mustard popular in Palestine and would be either 10 or 25 ft (3 or 7.5 m) tall.
10 tn Grk “the birds of the sky” or “the birds of the heaven”; the Greek word οὐρανός (ouranos) may be translated either “sky” or “heaven,” depending on the context. The idiomatic expression “birds of the sky” refers to wild birds as opposed to domesticated fowl (cf. BDAG 809 s.v. πετεινόν).
11 sn The point of the parable seems to be that while the kingdom of God may appear to have insignificant and unnoticeable beginnings (i.e., in the ministry of Jesus), it will someday (i.e., at the second advent) be great and quite expansive. The kingdom, however, is not to be equated with the church, but rather the church is an expression of the kingdom. Also, there is important OT background in the image of the mustard seed that grew and became a tree: Ezek 17:22-24 pictures the reemergence of the Davidic house where people can find calm and shelter. Like the mustard seed, it would start out small but grow to significant size.
