This explanation of the good seeds can be found in all 3 synoptic gospels. Mark indicated that Jesus said that the seeds sown on good soil (καὶ ἐκεῖνοί εἰσιν οἱ ἐπὶ τὴν γῆν τὴν καλὴν σπαρέντες) are the people who hear the word (οἵτινες ἀκούουσιν τὸν λόγον). They accept it (καὶ παραδέχονται). They then bear good fruit (καὶ καρποφοροῦσιν). They yield either thirtyfold (ἓν τριάκοντα), sixtyfold (καὶ ἓν ἑξήκοντα), or a hundredfold (καὶ ἓν ἑκατόν). Mathew, chapter 13:23, has the reverse order of 100, 60, and 30, while Luke, chapter 8:15, has no number on the fruits of the harvest. Only about 25% of the seeds sown were effective. Thus, only about 25% of the people hearing the word of the kingdom will follow it. There had to be good circumstances or pre-depositions to hearing and understanding for the word or the seed to be effective. The seeds or the word that fell on the path, on the rocky ground, or the thorns were ineffective. However, even among the effective seeds that were on good soil, the word would have different results. Some would yield 30 times, some 60, and some 100. There was no magic formula. The circumstances among the good hearers would also bring about a variety of responses and effectiveness.
Mark said the seeds were the word (ὁ σπείρων τὸν λόγον), without any further clarification. Matthew, chapter 13:19 was more explicit with the seeds as the word of the kingdom (τὸν λόγον τῆς βασιλείας). Luke, chapter 8:11, was ever more specific when he explicitly said that seed was the word of God (τὸν λόγον τοῦ Θεοῦ). Mark said that the sower (ὁ σπείρων), either Jesus or his apostles, was sowing the word (τὸν λόγον σπείρει), the word of the kingdom, or the word of God into good ground, so that it might bear fruit.
This story about Jesus cursing the fig tree can be found in Mark, chapter 11:13-14, in a condensed form. Luke, chapter 13:6-9, has a parable about a fig tree that would not bear fruit. Jesus saw one fig tree by the side of the road (καὶ ἰδὼν συκῆν μίαν ἐπὶ τῆς ὁδοῦ). He went over to it (ἦλθεν ἐπ’ αὐτήν) but he found no fruit (καὶ οὐδὲν εὗρεν ἐν αὐτῇ), since only leaves were on it (εἰ μὴ φύλλα μόνον). He then said to the tree (καὶ λέγει αὐτῇ) that no fruit would ever come from that tree again (Οὐ μηκέτι ἐκ σοῦ καρπὸς γένηται εἰς τὸν αἰῶνα). Then the fig tree withered or dried up instantly (καὶ ἐξηράνθη παραχρῆμα ἡ συκῆ). When his disciples saw this (καὶ ἰδόντες οἱ μαθηταὶ), they were amazed and marveled (ἐθαύμασαν). They wondered about this and said (λέγοντες). “How did this fig tree wither immediately (Πῶς παραχρῆμα ἐξηράνθη ἡ συκῆ)?” Even his disciples were amazed about this withering fig tree.
Yahweh, via Jeremiah, wants to bless those who trust in him. They will be blessed if their trust rests with and in Yahweh. They will be like a tree planted by water with good roots. They, like the tree, will not fear when heat comes, because this well watered tree will stay green. Even if there is a drought, this tree will not be anxious, since it will not cease to bear fruit. Everything depends on trust.
He has not devised wicked things against the Lord.
Special favor will be shown him
For his faithfulness.
There will be a place of great delight
In the temple of the Lord.
The fruit of good labors is renowned.
The root of understanding does not fail.”
This author then praises or calls the barren woman and the eunuch blessed or blissful (μακαρία). Both of these groups of people were considered outcasts of society because of their sterility. These barren women are those who were not defiled. They had not entered into a sinful union. They will bear fruit when their souls would be examined (ἐπισκοπῇ ψυχῶν). The eunuchs should have not done any lawless actions. They will not have devised anything wicked against the Lord (κατὰ τοῦ Κυρίου πονηρά). They will receive special favors because they were faithful. They will have a special place in the Temple of the Lord (ἐν ναῷ Κυρίου θυμηρέστερος). This is a reference to some kind of eternal reward. The fruits of a good life and understanding will not fail.
