Jimmy, until Yeshua died, The House of Israel was not eligible under Torah to find new faith through the grace of Yehova.
Torah says that if a man divorce a woman, she cannot marry another unless her husband is dead.
Yeshua’s death released the House of Israel to be remarried under Torah.
Torah governs all things in the kingdom of Yehova.
Since as Yeshua stated in his ministry, he came only for his lost sheep of the House of Israel, this was a great mystery both on Earth, and among his angels.
Interesting theory, but does not seem to coincide with this verse:
John 10:14 “I am the good shepherd; I know my sheep and my sheep know me—
15 just as the Father knows me and I know the Father—and I lay down my life for the sheep.
16 I have other sheep that are not of this sheep pen. I must bring them also. They too will listen to my voice, and there shall be one flock and one shepherd.
Regarding what the Angels were interested to learn, Peter seems to indicate the subject they desired to understand was the suffering of the Christ and the Gospel, to wit:
1 Peter 1:10 Concerning this salvation, the prophets, who spoke of the grace that was to come to you, searched intently and with the greatest care,
11 trying 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.
12 It 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.
