“Then the disciples came.
They said to Jesus.
‘Why do you speak
To them in parables?’”
Καὶ προσελθόντες οἱ μαθηταὶ εἶπαν αὐτῷ Διὰ τί ἐν παραβολαῖς λαλεῖς αὐτοῖς;
This question to Jesus can be found in all 3 synoptic gospels, Mark, chapter 4:10, and Luke, chapter 8:9. The disciples came to Jesus (Καὶ προσελθόντες οἱ μαθηταὶ). They wanted to know why Jesus spoke to the crowds in parables (εἶπαν αὐτῷ Διὰ τί ἐν παραβολαῖς λαλεῖς αὐτοῖς). The disciples were confused about the use of parables.
