Luke 24:18

knowest not, &c.--If he knew not the events of the last few days in Jerusalem, he must be a mere sojourner; if he did, how could he suppose they would be talking of anything else? How artless all this!

Our Lord Jesus went gloriously down to death, in spite of the malice of his enemies, who did all they could to make his death ignominious; but he rose again more gloriously, of which we have an account in this chapter; and the proofs and evidences of Christ's resurrection are more fully related by this evangelist than they were by Matthew and Mark. Here is, I. Assurance given by two angels, to the woman who visited the sepulchre, that the Lord Jesus was risen from the dead, according to his own word, to which the angels refer them (Luk 24:1-7), and the report of this to the apostles (Luk 24:8-11). II. The visit which Peter made to the sepulchre, and his discoveries there (Luk 24:12). III. Christ's conference with the two disciples that were going to Emmaus, and his making himself known to them (v. 13-35). IV. His appearing to the eleven disciples themselves, the same day at evening (Luk 24:36-49). V. The farewell he gave them, his ascension into heaven, and the joy and praise of his disciples whom he left behind (Luk 24:50-53).

24:18 the only person in Jerusalem who hasn’t heard about all the things: The Romans conducted crucifixions at major public crossroads to make an example of the victims and warn others against revolt. It was unthinkable to these disciples that a Passover pilgrim would not have heard of Jesus’ crucifixion.
