Verse 9. - And he said, Who hath ears to hear, let him hear. St. Luke (Luke 8:8) bus a stronger word than (ἔλεγεν) "he said." He (Luke 8:8) has (ἐφώνει) "he cried." Our Lord uses this expression, "he that hath ears to hear," etc, when the subject-matter is figurative or obscure, as though to rouse the attention of his hearers. He has "ears to hear" who diligently attends to the words of Christ, that he may ponder and obey them. Many heard him out of curiosity, that they might bear something new, or learned, or brilliant; not that they might lay to heart the things which they heard, and endeavor to practice them in their lives. And so it is with those who go to hear sermons on account of the fame of the preacher, and not that they may learn to amend their lives; and thus the words of Jehovah to Ezekiel (Ezekiel 33:32) are fulfilled, "And, lo, thou art unto them as a very lovely song of one that hath a pleasant voice, and can play well on an instrument: for they hear thy words, but they do them not."

4:1-20 This parable contained instruction so important, that all capable of hearing were bound to attend to it. There are many things we are concerned to know; and if we understand not the plain truths of the gospel, how shall we learn those more difficult! It will help us to value the privileges we enjoy as disciples of Christ, if we seriously consider the deplorable state of all who have not such privileges. In the great field of the church, the word of God is dispensed to all. Of the many that hear the word of the gospel, but few receive it, so as to bring forth fruit. Many are much affected with the word for the present, who yet receive no abiding benefit. The word does not leave abiding impressions upon the minds of men, because their hearts are not duly disposed to receive it. The devil is very busy about careless hearers, as the fowls of the air go about the seed that lies above ground. Many continue in a barren, false profession, and go down to hell. Impressions that are not deep, will not last. Many do not mind heart-work, without which religion is nothing. Others are hindered from profiting by the word of God, by abundance of the world. And those who have but little of the world, may yet be ruined by indulging the body. God expects and requires fruit from those who enjoy the gospel, a temper of mind and Christian graces daily exercised, Christian duties duly performed. Let us look to the Lord, that by his new-creating grace our hearts may become good ground, and that the good seed of the word may produce in our lives those good words and works which are through Jesus Christ, to the praise and glory of God the Father.And he said unto them,.... To the multitude of hearers that were on the sea shore attending to the word preached, and among whom, doubtless, there were all those sorts of hearers mentioned in this parable:

he that hath ears to hear, let him hear: observe, and take notice of what has been said, as being of the greatest moment and importance: for a larger explanation and illustration of this parable, see the notes on Matthew 13:3.
