The Old Testament mentions the righteous dead being bodily resurrected out of their graves.
•Isaiah 26:19 - "Thy dead men shall live, together with my dead body shall they arise. Awake and sing ye that dwell in dust: for thy dew is as the dew of herbs, and the earth shall cast out the dead."
•Job 14:13-15 - "O that thou wouldest hide me in the grave, that thou wouldest keep me secret, until thy wrath be past, that thou wouldest appoint me a set time, and remember me! If a man die, shall he live again? all the days of my appointed time will I wait, till my change come. Thou shalt call, and I will answer thee: thou wilt have a desire to the work of thine hands." This "call" was the same "voice of the Son of God" in John 5:25-29 which Christ said was going to wake the dead. And the "change" in Job is the same as that "change" for the mortal remains of all the dead saints mentioned in 1 Cor. 15:51-55.
The Old Testament mentions the gathering of the resurrected saints together at Christ's coming.
•Genesis 49:10 - "The sceptre shall not depart from Judah, nor a lawgiver from between his feet UNTIL Shiloh come, and to Him shall the gathering of the people be." Jacob's prophecy of "Shiloh" is about Christ Jesus, telling his sons that Judah would maintain the right to rule and govern among the 12 tribes UNTIL Christ Jesus came and gathered His people, the resurrected saints. These tribal distinctions disappeared with the destruction of the temple in AD 70, with Judah exercising that God-given right of dominance over the other tribes up to that point (as in Zechariah 12:4-7). This "gathering of the people" predicted by Jacob in Genesis 49:10 is the same as the 2 Thess. 2 "our gathering together unto Him".
Joseph knew very well what this Genesis 49:10 prediction of his father meant, which is why he later requested in faith that his bones be taken back to Hebron and buried with his father in the cave of Machpelah. He wanted to be in the same location as his father when the gathering together of the people of God in a resurrection would occur.
But the Old Testament never mentions any such thing as the living believers who had never died expecting to be translated so that they did not have to pass through the physical death process. This is the typical misunderstanding of what the rapture includes, and it is NOT how the Scriptures all describe the believers being gathered together and taken to heaven with Christ.
