Luke indicated that Jesus said that those seeds that fell among the thorns (τὸ δὲ εἰς τὰς ἀκάνθας πεσόν) were like the ones who hear the word (οὗτοί εἰσιν οἱ ἀκούσαντες), but as they go on their way (πορευόμενοι), they are choked or crowded out (συνπνίγονται) by the cares (καὶ ὑπὸ μεριμνῶν), the riches (καὶ πλούτου), and the pleasures of life (καὶ ἡδονῶν τοῦ βίου). Their fruit does not mature (καὶ οὐ τελεσφοροῦσιν). This explanation about the seeds among the thorns can be found in all 3 synoptic gospels, Mark, chapter 4:18-19, Matthew, chapter 13:22, and here, with Matthew closer to Mark. Both Matthew and Mark said that the seeds sown among the thorns were the ones who heard the words of the kingdom, but the cares and anxiety of this present age, as well as the allure or deceit of material wealth, choked or crowded out the words. Thus, it yielded nothing, because it was barren. The thorns were the cares about physical riches that choked off the growth of the seeds or the words of the kingdom. There had to be good circumstances or pre-depositions to hearing and understanding for the word or the seed to be effective. There had to be follow up or acting out on the word for it to mature into a full mature faith belief in Jesus Christ. Have the seeds of the word of God matured in you?
This saying about the camel and the eye of a needle can be found in Matthew, chapter 19:24, and Luke, chapter 18:25, almost word for word. Mark indicated that Jesus said that it would be easier (εὐκοπώτερόν ἐστιν) for a camel to go or pass through the eye of a needle (κάμηλον διὰ τῆς τρυμαλιᾶς τῆς ῥαφίδος διελθεῖν), that was used for sewing, than for a wealthy rich man to enter the kingdom of God (ἢ πλούσιον εἰς τὴν βασιλείαν τοῦ Θεοῦ εἰσελθεῖν). This was a follow up to the obstacles of wealth. Everyone knew that it would be impossible for a camel to go through a sewing needle eye or a needle opening. There was no needle gate in Jerusalem, since this was about a sewing needle.
This saying about temptations and stumbling blocks is unique to Matthew. However, it is a follow up to the preceding verses. The world is cursed (Οὐαὶ τῷ κόσμῳ) because of these stumbling blocks, snares, or temptations (ἀπὸ τῶν σκανδάλων). These snares, stumbling blocks, or temptations are necessarily bound to happen (ἀνάγκη γὰρ ἐλθεῖν τὰ σκάνδαλα,). However cursed is the man or person (, πλὴν οὐαὶ τῷ ἀνθρώπῳ) by whom these stumbling blocks or temptations come (δι’ οὗ τὸ σκάνδαλον ἔρχεται). Temptations and snares are to be cursed. But also, the humans or people who bring these temptations, snares, stumbling blocks should also be cursed.
