1 Peter 1:10-12

10Concerning this salvation, the prophets, who spoke of the grace that was to come to you, searched intently and with the greatest care, 11trying to find out the time and circumstances to which the Spirit of Christ in them was pointing when he predicted the sufferings of the Messiah and the glories that would follow. 12It was revealed to them that they were not serving themselves but you, when they spoke of the things that have now been told you by those who have preached the gospel to you by the Holy Spirit sent from heaven. Even angels long to look into these things.
