“When Jesus had finished
All these sayings,
To his disciples.”
Καὶ ἐγένετο ὅτε ἐτέλεσεν ὁ Ἰησοῦς πάντας τοὺς λόγους τούτους, εἶπεν τοῖς μαθηταῖς αὐτοῦ
This is unique to Matthew. When Jesus had finished or completed all these sayings (Καὶ ἐγένετο ὅτε ἐτέλεσεν ὁ Ἰησοῦς πάντας τοὺς λόγους τούτους), he then spoke to his disciples (εἶπεν τοῖς μαθηταῖς αὐτοῦ). Basically, Matthew was indicating that the public ministry, his preaching, his sayings, and parables were now complete. From now on, he would only speak with his trusted disciples, and more particularly with his 12-man leadership team of apostles. There would be no more large crowds listening to Jesus.
