Matthew 21:37

Reverence - To show respect or fear.

Last of all he sent - his son - This requires no comment. Our Lord plainly means himself.

They will reverence - Εντραπησονται, they will reflect upon their conduct and blush for shame because of it, when they see my son. So the Syric and Persic.

Last of all ... - Mark adds that this was an only son, greatly beloved.

This beautifully and most tenderly exhibits the love of God in sending his only Son, Jesus Christ, into the world to die for people. Long had he sent the prophets, and they had been persecuted and slain. There was no use in sending any more prophets to the people. They had done all that they could do. God had one only-begotten and well-beloved Son, whom he might send, and whom the world "ought" to reverence even as they should the Father, John 5:23. God is often represented in the Bible as giving his Son, his only-begotten and wellbeloved Son, for a lost world, John 3:16-17; 1 John 4:9, 1 John 4:14; Romans 8:3, Romans 8:32; Galatians 4:4.

Saying, They will reverence my son - To "reverence" means to honor, to esteem, to show deference to. It is that feeling which we have in the presence of one who is greatly our superior. It means to give to such a person, in our feelings and our deportment, the honor which is due to his rank and character.
