It pointed to the feast of Pentecost which equates to the wilderness or the holy place or second son of the feasts prepared by a woman (which the three show one angle of a view of this process), was now in us and the process of the two becoming one in us begun, and why Peter said upon all flesh.
The process brings about a consensus and this consensus, or the two that were made one, which is now a process in us, whom Christ is the foundation of and an anchor of our soul, (Where's Christ, Where's beyond the veil, Where's the throne, Where's the Father ...), is what the whole of the OT, starting from one, leads to, this consensus in the person of Christ Jesus, Christ himself testifying of the way, truth and the life, and Jesus becoming it, in the flesh, on the cross.
You are right, the Bible is one cohesive narrative, like a garment without a seam and he is at the end of every thread, pun intended.
