(23) He was very sorrowful.--St. Luke's word stands half-way between St. Matthew's "sorrowing" and St. Mark's vivid "lowering" or "frowning." (See Note on Mark 10:22.)

He was very rich.--St. Luke's equivalent for he had great possessions. There is, perhaps, something suggestive, especially on the view which has been taken as to the identity of the young ruler, and the purport of the parable of the Rich Man and Lazarus, in the use of the very same adjective as had been employed in that parable.

Verse 23. - And when he heard this, he was very sorrowful: for he was very rich. St. Mark adds (a memory of Peter's) that when he heard this the ruler went away frowning, with a lowering look. This was too much. He could not, even at the bidding of that loved Teacher, give up the pleasant life he loved so well, the things he prized so highly; so silently and sadly he turned away. The 'Gospel of the Hebrews,' a very ancient document, dating from the first days of the faith, a few fragments only of which have come down to us in quotations in the Fathers, thus describes the scene: "Then the rich man began to scratch his head, for that was not to his mind. And the Lord said to him, How then canst thou say, I have kept the Law; for it is written in the Law, Thou shalt love thy neighbour as thyself; and, lo! many of thy brethren, children of Abraham, live in the gutter, and die of hunger, while thy table is loaded with good things, and nothing is sent out to them?" (quoted by Origen, in Matthew 19.). Dante calls this "The Great Refusal," and represents the shade of the young ruler among the throng of the useless, of those who faced both ways (' Inferno,' 10:27). It is worthy of notice that there was no angry retort from the wealthy ruler, no scornful, cynical smile of derision, as we read of among the covetous, wealthy Pharisees (Luke 16:14). Still, in the heart of this seeker after the true wisdom there was a sore conflict. Grieving, sorrow-stricken, with gloomy looks, he turned away in silence.

18:18-30 Many have a great deal in them very commendable, yet perish for lack of some one thing; so this ruler could not bear Christ's terms, which would part between him and his estate. Many who are loth to leave Christ, yet do leave him. After a long struggle between their convictions and their corruptions, their corruptions carry the day. They are very sorry that they cannot serve both; but if one must be quitted, it shall be their God, not their wordly gain. Their boasted obedience will be found mere outside show; the love of the world in some form or other lies at the root. Men are apt to speak too much of what they have left and lost, of what they have done and suffered for Christ, as Peter did. But we should rather be ashamed that there has been any regret or difficulty in doing it.And when he heard this,.... That one thing was wanting, and what that was, which was to part with all his worldly substance, and follow Christ;

he was very sorrowful, for he was very rich; See Gill on Matthew 19:22.
