“Then Jesus said
To them.
‘Prophets are not
Without honor,
Except in their hometown,
Among their own relatives,
And in their own house.’”
καὶ ἔλεγεν αὐτοῖς ὁ Ἰησοῦς ὅτι Οὐκ ἔστιν προφήτης ἄτιμος εἰ μὴ ἐν τῇ πατρίδι αὐτοῦ καὶ ἐν τοῖς συγγενεῦσιν αὐτοῦ καὶ ἐν τῇ οἰκίᾳ αὐτοῦ.
This saying about no honor for prophets in their hometown can be found in all 3 synoptic gospels, Matthew, chapter 13:57, and Luke, chapter 4:24, and here. Mark said that Jesus told them (καὶ ἔλεγεν αὐτοῖς ὁ Ἰησοῦς) that prophets are not without honor or not despised (ὅτι Οὐκ ἔστιν προφήτης ἄτιμος), except in their own country (εἰ μὴ ἐν τῇ πατρίδι αὐτοῦ), among their own relatives (καὶ ἐν τοῖς συγγενεῦσιν αὐτοῦ), and in their own house (καὶ ἐν τῇ οἰκίᾳ αὐτοῦ). They would be not honored among their own hometown, relatives, and in their own house. It is always more difficult in your own home town. This was common among the Old Testament prophets, especially the Israelite prophets Jeremiah and Amos.
