“Jesus said.
‘Let anyone with ears
To hear,
Listen.’”
καὶ ἔλεγεν Ὃς ἔχει ὦτα ἀκούειν ἀκουέτω.
This warning at the end of the sower parable can be found in all 3 synoptic gospels, in Matthew, chapter 13:8, and in Luke, chapter 8:8, and here. Jesus warned them as he said (καὶ ἔλεγεν) that anyone with ears to hear should listen (Ὃς ἔχει ὦτα ἀκούειν ἀκουέτω) to this parable. Jesus often mentioned the importance of hearing and listening.
