In the last 3 verses of Matthew 9 we read of the Lord speaking about sending out workers into His harvest field, this chapter tells us He cares, and so He sends out the laborers — His 12 apostles. He is the Lord of the harvest. But to properly understand the book of Matthew, you need to remember that it is mainly to Israel that all refers. Verse 5 makes this plain. They were not to go outside the borders of Israel. They were to preach that the kingdom of heaven was going to be set up. They were to present the Messiah.
V.5-15 The instructions in detail: what they were to say, and where they were to say it.
V.16-42 More general statements for the disciples. All this was said and done before He was rejected, and therefore it never was carried out. The Lord Jesus when He comes in power and glory — when we believers come back with Him. “E” on your chart — then He will carry out all this chapter. For the believer now it is a kingdom in mystery for there is no visible king.
