(45) Then opened he their understanding.--Assuming, as we must assume, that this was the same meeting of the Lord with His disciples as that reported in John 20:22, we have here that which corresponds with the gift of the Holy Spirit He then imparted to them. They were conscious of a new spiritual power of insight and knowledge which they had not possessed before. St. Luke's report, as derived probably at second or third hand, through Joanna or others, is naturally more vague than that which comes from the eye-witness.

Verse 45. - Then opened he their understanding, that they might understand the Scriptures. Assuming (as is most probably the case) that vers. 44 and 45 refer to words spoken by Jesus on the first Easter evening to the eleven and to Cleopas and his friend, then the way in which he opened their understanding is described by St. John (John 20:22) thus: "He breathed on them, and saith unto them, Receive ye the Holy Ghost." Among the new powers bestowed on them by this Divine gift, St. Luke especially dwells on the spiritual insight henceforth possessed by these men into the Scriptures of the Old Testament, hitherto only partly understood. This power was doubtless one of the great instruments of their success as preachers. In the next four verses (46-49) St. Luke evidently briefly summarizes the Master's great sayings, some probably spoken in the course of the walk to Emmaus, some on that first Easter evening, some on other occasions during the forty days which elapsed between the Resurrection and the Ascension. The introductory words, "and said unto them" (ver. 46), seem the commencement cf. this summary,

24:36-49 Jesus appeared in a miraculous manner, assuring the disciples of his peace, though they had so lately forsaken him, and promising spiritual peace with every blessing. Many troublesome thoughts which disquiet our minds, rise from mistakes concerning Christ. All the troublesome thoughts which rise in our hearts at any time, are known to the Lord Jesus, and are displeasing to him. He spake with them on their unreasonable unbelief. Nothing had passed but what was foretold by the prophets, and necessary for the salvation of sinners. And now all men should be taught the nature and necessity of repentance, in order to the forgiveness of their sins. And these blessings were to be sought for, by faith in the name of Jesus. Christ by his Spirit works on the minds of men. Even good men need to have their understandings opened. But that we may have right thoughts of Christ, there needs no more than to be made to understand the Scriptures.Then opened he their understanding,.... He not only opened their hearts, to attend to what he said, and the proofs he gave of his resurrection from the dead in a true body; but he removed the veil from the eyes of their minds, and gave them an understanding of the sacred writings, respecting this matter:

that they might understand the Scriptures; concerning his sufferings, death, and resurrection, which they were very ignorant of before, and which were as a sealed book unto them, John 20:9 though they had been from their infancy brought up to the reading of the Scriptures, and had had the advantage of Christ's ministry for some years; which shows the necessity of the special illumination of the Spirit, and the influence of his grace to remove the darkness of the mind, and give the true sense of the sacred writings.
