Jesus emphasized the importance of knowing and understanding biblical prophecy on multiple occasions. Don't forget, the Olivet Discourse was given just before His arrest, and immediately upon His resurrection He was again, emphasizing the importance of prophecy and explained that the to the apostles and the two men leaving Jerusalem for Emma's. It was obviously quite important to Jesus that we know the signs of His coming:
35 “Be dressed ready for service and keep your lamps burning,36 like servants waiting for their master to return from a wedding banquet, so that when he comes and knocks they can immediately open the door for him.37It will be good for those servants whose master finds them watching when he comes. Truly I tell you, he will dress himself to serve, will have them recline at the table and will come and wait on them.38It will be good for those servants whose master finds them ready, even if he comes in the middle of the night or toward daybreak.39 But understand this: If the owner of the house had known at what hour the thief was coming, he would not have let his house be broken into.40You also must be ready, because the Son of Man will come at an hour when you do not expect him.”
54 He said to the crowd: “When you see a cloud rising in the west, immediately you say, ‘It’s going to rain,’ and it does.55 And when the south wind blows, you say, ‘It’s going to be hot,’ and it is.56 Hypocrites! You know how to interpret the appearance of the earth and the sky. How is it that you don’t know how to interpret this present time?
On the Road to Emmaus
13 Now that same day two of them were going to a village called Emmaus, about seven miles[a] from Jerusalem.14 They were talking with each other about everything that had happened.15 As they talked and discussed these things with each other, Jesus himself came up and walked along with them;16 but they were kept from recognizing him.
17 He asked them, “What are you discussing together as you walk along?”
They stood still, their faces downcast.18 One of them, named Cleopas, asked him, “Are you the only one visiting Jerusalem who does not know the things that have happened there in these days?”
19 “What things?” he asked.
“About Jesus of Nazareth,” they replied. “He was a prophet, powerful in word and deed before God and all the people.20 The chief priests and our rulers handed him over to be sentenced to death, and they crucified him;21 but we had hoped that he was the one who was going to redeem Israel. And what is more, it is the third day since all this took place.22 In addition, some of our women amazed us. They went to the tomb early this morning23 but didn’t find his body. They came and told us that they had seen a vision of angels, who said he was alive.24 Then some of our companions went to the tomb and found it just as the women had said, but they did not see Jesus.”
25 He said to them, “How foolish you are, and how slow to believe all that the prophets have spoken!26 Did not the Messiah have to suffer these things and then enter his glory?”27 And beginning with Moses and all the Prophets, he explained to them what was said in all the Scriptures concerning himself.
36 While they were still talking about this, Jesus himself stood among them and said to them, “Peace be with you.”
37 They were startled and frightened, thinking they saw a ghost.38 He said to them, “Why are you troubled, and why do doubts rise in your minds?39 Look at my hands and my feet. It is I myself! Touch me and see; a ghost does not have flesh and bones, as you see I have.”
40 When he had said this, he showed them his hands and feet.41 And while they still did not believe it because of joy and amazement, he asked them, “Do you have anything here to eat?”42 They gave him a piece of broiled fish,43 and he took it and ate it in their presence.
44 He said to them, “This is what I told you while I was still with you: Everything must be fulfilled that is written about me in the Law of Moses, the Prophets and the Psalms.”
So what were these prophecies that they didn't understand?
