Discovery BoxMark 4:26-32 
Context4:26 He also said, “The kingdom of God is like someone who spreads seed on the ground. 4:27 He goes to sleep and gets up, night and day, and the seed sprouts and grows, though he does not know how. 4:28 By itself the soil produces a crop, first the stalk, then the head, then the full grain in the head. 4:29 And when the grain is ripe, he sends in the sickle 1 because the harvest has come.” 2
4:30 He also asked, “To what can we compare the kingdom of God, or what parable can we use to present it? 4:31 It is like a mustard seed 3 that when sown in the ground, even though it is the smallest of all the seeds in the ground – 4:32 when it is sown, it grows up, 4 becomes the greatest of all garden plants, and grows large branches so that the wild birds 5 can nest in its shade.” 6
1 tn The Greek word εὐθύς (euqus, often translated “immediately” or “right away”) has not been translated here. It sometimes occurs with a weakened, inferential use (BDAG 406 s.v. 2), not contributing significantly to the flow of the narrative. For further discussion, see R. J. Decker, Temporal Deixis of the Greek Verb in the Gospel of Mark with Reference to Verbal Aspect (SBG 10), 73-77.
2 sn Because the harvest has come. This parable is found only in Mark (cf. Matt 13:24-30) and presents a complete picture of the coming of God’s kingdom: (1) sowing; (2) growth; (3) harvest. Some understand the parable as a reference to evangelism. While this is certainly involved, it does not seem to be the central idea. In contrast to the parable of the sower which emphasizes the quality of the different soils, this parable emphasizes the power of the seed to cause growth (with the clear implication that the mysterious growth of the kingdom is accomplished by God), apart from human understanding and observation.
3 sn Mustard seeds are known for their tiny size.
4 tn Mark 4:31-32 is fairly awkward in Greek. Literally the sentence reads as follows: “As a mustard seed, which when sown in the earth, being the smallest of all the seeds in the earth, and when it is sown, it grows up…” The structure has been rendered in more idiomatic English, although some of the awkward structure has been retained for rhetorical effect.
5 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).
6 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.
