There is no resurrection when the Two Witnesses are raised to life and ascend to heaven. Heb 9:27 says that everyone is appointed to die ONCE, and then the judgment. There are 2 OT prophets who NEVER died physically, Enoch and Elijah. They get that experience at the hands of Satan. They go bodily up to heaven. There is no mention of receiving a glorified body. Remember that there are several accounts in the OT of dead people coming back to life as well as numerous accounts in the gospels of Jesus raising dead people.
Yet, Acts 26:23 tells us who received the FIRST glorified, resurrected body; Jesus Himself.
Acts 26:23 - that the Messiah would suffer and, as the first to rise from the dead, would bring the message of light to his own people and to the Gentiles.”
This is confirmed in 1 Cor 15:23 - But each in turn: Christ, the firstfruits; then, when he comes, those who belong to him.
Notice also what else the verse tells us: "those who belong to Him" is a reference to EVERY believer from Adam forward. And the verse also tells us WHEN that single resurrection of ALL believers will occur: "when He comes".
When the Bible speaks of the "coming of the Lord" it is referring to His Second Advent. The OT prophesies about just two advents. His first advent was as a baby to become the Suffering Servant. His second advent will be as the King of kings, and Lord of lords.
So, the ascension of the Two Witnesses cannot be a resurrection where they receive glorified bodies. They will get theirs per 1 Thess 4:17 and 1 Cor 15:51-53. It will be "when He comes" at the Second Advent.
