“And he said unto them, These are the words which I spake unto you, while I was yet with you, that all things must be fulfilled, which were written in the law of Moses, and in the prophets, and in the psalms, concerning me.”
King James Version (KJV)
24:44 And he said - On the day of his ascension. In the law, and the prophets, and the psalms - The prophecies as well as types, relating to the Messiah, are contained either in the books of Moses (usually called the law) in the Psalms, or in the writings of the prophets; little being said directly concerning him in the historical books.
Lu 24:44-48 And he said unto them. Between verses 43 and 44, Luke passes over an interval of weeks, and many appearances of the Risen Christ, to come at once to the event of his Ascension. The Lord, about to send them forth to preach, "opens their mind that they might understand the Scriptures", and then repeats the Commission, before given in Galilee. He requires that (1) Repentance, (2) Remission of Sins, (3) Shall be Preached in his Name, (4) Unto All Nations, (5) Beginning at Jerusalem. This was literally obeyed on the day of Pentecost.
