What's the biblical basis for Abraham, David, etc. to be raised in the first resurrection?

We are told David is dead. >For David, after he had served God’s purpose in his own generation, fell asleep, and was buried among his fathers and underwent decay Acts 13:36 We could include any of 'God's men and women of old' in this - Moses, the prophets etc. Whenever one of these OT servants is raised, we would assume they will be raised together. We also are told that Moses and Elijah were presented in a *vision* on the mount with Jesus and the voice of God and were not actually alive at this time. And as they are coming down from the mount, Jesus charged them, saying, 'Say to no one the vision, till the Son of Man out of the dead may rise.' Matt 17:9 Youngs, NASB, BLB Do we have firm indication that these servants before Jesus will be raised with the saints at his return?
