I will have to disagree with you, Ezekiel 34,36, & 37, they are all about redemption through Christ and the spirit.
Salvation means redemption, deliverance, protection. All these prophecies are fulfilled by Christ and through Christ, salvation for Israel come no other way.
Just look at Ezekiel 34:12, he talks about gathering the flock on a day of clouds and darkness; that is the shepherd with the one flock and references the SAME DARKNESS mentioned in MATTHEW 24, right before the shepherd gathers the elect.
36&37, both speak of a pasturing on the mountains of Israel, but it's not the earthly Israel. The new spirit and new heart mentioned, that's the new covenant for the one flock under Christ, and his kingdom in which the flock enters through the gate is not of this Earth.
Paul understood Zion as the heavenly Jerusalem and quoted OT, I would recommend trying to see HOW he new the OT was talking about the Heavenly Jerusalem.
Peter reveals how the prophets who predicted Christ's coming also talked about the salvation and future glories that would also follow
1st Peter 1:10Concerning 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 Christ 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.
