See the notes at Matthew 22:34-40.
Perceiving that he answered them well - That is, with wisdom, and with a proper understanding of the law. In this case the opinion of the Saviour corresponded with that of the Pharisees; and the question which this scribe put to him now seems to have been one of the very few candid inquiries of him by the Jews for the purpose of obtaining information. Jesus answered it in the spirit of kindness, and commended the conduct of the man.
Hear, O Israel! - This was said to call the attention of the Jews to the great importance of the truth about to be proclaimed. See Deuteronomy 6:4-5.
The Lord our God ... - Literally, “Yahweh, our God, is one Yahweh.” The other nations worshipped many gods, but the God of the Jews was one, and one only. יהוה Yahweh was undivided; and this great truth it was the design of the separation of the Jewish people from other nations to keep in mind. This was the “peculiar” truth which was communicated to the Jews, and this they were required to keep and remember forever.
And thou shalt love ... - If Yahweh was the “only” God, then they ought not to love any other being supremely - then they might not bow down before any idol. They were required to love God above all other beings or things, and with all the faculties of their minds. See the notes at Matthew 22:37.
This answer of the scribe is not found in Matthew.
Is more than all - Is of more importance and value.
Discreetly - Wisely, according to truth.
Not far from the kingdom of God - Thou who dost prefer the “internal” to the “external” worship of God - who hast so just a view of the requirements of the law - canst easily become a follower of me, and art almost fit to be numbered among my disciples. This shows that a proper understanding of the Old Testament, of its laws and requirements, would prepare the mind for Christianity, and suit a person at once to embrace it when presented. One system is grafted on the other, agreeably to Galatians 3:24.
And no man after that durst ask him any question - That is, no one of the scribes, the Pharisees, or the Sadducees durst ask him a question for the purpose of “tempting” him or entangling him. He had completely silenced them. It does not appear, however, but that his “disciples” dared to ask him questions for the purpose of information.
