Matthew 13:32

13:32 It is the smallest of all the seeds, but when it has grown it is the greatest garden plant and becomes a tree, ¹  so that the wild birds ²  come and nest in its branches.” ³ 

Matthew 13:38

13:38 The field is the world and the good seed are the people ⁴  of the kingdom. The weeds are the people ⁵  of the evil one,

Matthew 22:24-25

22:24 “Teacher, Moses said, ‘If a man dies without having children, his brother must marry the widow and father children ⁶  for his brother.’ ⁷  22:25 Now there were seven brothers among us. The first one married and died, and since he had no children he left his wife to his brother.

¹ sn This is rhetorical hyperbole, since technically a mustard plant is not a tree. This could refer to one of two types of mustard plant popular in Palestine and would be either ten or twenty-five ft (3 or 7.5 m) tall.

² 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).

³ 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.

⁴ tn Grk “the sons of the kingdom.” This idiom refers to people who should properly be, or were traditionally regarded as, a part of God’s kingdom. L&N 11.13 translates the phrase: “people of God’s kingdom, God’s people.”

⁵ tn Grk “the sons of the evil one.” See the preceding note on the phrase “people of the kingdom” earlier in this verse, which is the opposite of this phrase. See also L&N 9.4; 11.13; 11.14.

⁷ tn Grk “and raise up seed,” an idiom for fathering children (L&N 23.59).

⁸ sn A quotation from Deut 25:5. This practice is called levirate marriage (see also Ruth 4:1-12; Mishnah, m. Yevamot; Josephus, Ant. 4.8.23 [4.254-256]). The levirate law is described in Deut 25:5-10. The brother of a man who died without a son had an obligation to marry his brother’s widow. This served several purposes: It provided for the widow in a society where a widow with no children to care for her would be reduced to begging, and it preserved the name of the deceased, who would be regarded as the legal father of the first son produced from that marriage.
