1 Peter 1:10-12

10Concerning this salvation, the prophets who foretold the grace to come to you searched and investigated carefully, 11trying to determine the time and setting to which the Spirit of Christ in them was pointing when He predicted the sufferings of Christ and the glories to follow.

12It was revealed to them that they were not serving themselves, but you, when they foretold the things now announced by those who preached the gospel to you by the Holy Spirit sent from heaven. Even angels long to look into these things.
