What does the Bible say about the desire of prophets and angels?

In Ephesians 3:5-10, the Apostle Paul highlights that the prophets of old diligently searched for knowledge of Christ, even though the full revelation was not available to them as it is to us today. They inquired deeply into salvation and the grace that would come to the Gentiles. Similarly, angels are portrayed in 1 Peter 1:12 as desirous to look into the things now revealed through the church. They want to understand God's manifold wisdom manifested through the gospel and His eternal purposes. This dual desire of both prophets and angels emphasizes the profound significance of salvation history and the revelation of Christ's redemptive work.
