Luke 10:23-24 New American Bible (Revised Edition) (NABRE)
23 Turning to the disciples in private he said, “Blessed are the eyes that see what you see. 24 For I say to you, many prophets and kings desired to see what you see, but did not see it, and to hear what you hear, but did not hear it.”
The Greatest Commandment.
1 Peter 1:10-12 New American Bible (Revised Edition) (NABRE)
10 [a]Concerning this salvation, prophets who prophesied about the grace that was to be yours searched and investigated it, 11 investigating the time and circumstances that the Spirit of Christ within them indicated when it testified in advance to the sufferings destined for Christ and the glories to follow them. 12 It was revealed to them that they were serving not themselves but you with regard to the things that have now been announced to you by those who preached the good news to you [through] the holy Spirit sent from heaven, things into which angels longed to look.
