Isaiah 53 tells about the final prophet of Israelite, the Messiah after death (due to end of prolonged period of life), he will bear sin/guilt for many (Israelites) and intercedes transgressing Jews; not bear sin of world or new covenant as interpreted by Roman Christian authors. As Messiah was sent for the Israelites.
Nowhere can you find anything about waking up after death and stay on earth for forty days before lifted to heaven in Isaiah 53:8. The reason the Messiah needed to be taken away from land of living is that if he continues to stay on earth, the law of life on earth will apply onto Messiah. From baby the Messiah grows until adulthood. If he stays on earth, he will become old age and die due to old age or die due to being killed by enemies.
As Messiah vanish from land of Israel lifted to heaven, 53:9 mentioned about the Messiah's grave among the wicked and transgressing Jews. But if the Messiah grave is known to wicked Jews, then whose body was inside the grave? (Quran mentioned about 'the person' being crucified)
God tested His servant by bruising the Messiah in 53:10 as the transgressing Jews will take away his life for sin/guilt. But God made it clear in later part of verse that the servant will prolong his days. God did not say "He shall prolong his revived days". Also notice that it says prolong which means there will be an end to the Messiah life. Thus the Messiah is not eternal living creature. And how will the life be prolong? Certainly the Messiah will be raised and lifted to heaven by God and be given prolong life in heaven until the need to return for his second coming as commanded by God.
At the end of the Messiah prolonged life. The Messiah will certainly die. And like all other prophets in the afterlife, depending on their covenant of different location and era, the prophets will intercede for their followers's to overcome the follower sins by mediating and seeking more reward from God for their follower; this was described what will happen to Messiah and his followers as described in Isaiah 53:12
