The Pillars of The Door

Ver. 37, And thou shalt make for the hanging five pillars of shittim wood, and overlay them with gold, and their hooks shall be of gold: and thou shalt cast five sockets of brass for them.
And chapter 36:38, And the five pillars of it with their hooks: and he overlaid their chapiters and their fillets, (or suspending rods) with gold: but their five sockets were of brass.) As the four pillars of the vail represent the four-fold provision made by God in the divinely inspired histories of the life and death of the Lord Jesus, so the five pillars by which the hanging for the door is suspended, represent to us those gifts of the Spirit from a risen and ascended Christ, by which he is made known as the way, the truth and the life the gifts of the apostle and prophet, the evangelist, the, pastor and the teacher, corresponding with the five bars of the tabernacle, and with the cherubim on the mercy seat, and in the vail.
But while there are correspondences, there are also distinctions. The cherubim on the mercy seat signifying these gifts in their Divine and heavenly source. The cherubim on the vail, these gifts as possessed in all their fullness by the Lord Jesus when on earth. The five pillars of the door of the tent, the gifts as connected in their exercise with admission into the assembly. And the five bars of the tabernacle, the same gifts employed for the edification and compacting of the Church together.
This suggests the reason why there are no cherubim on the hanging for the door; as in the vail, —the truth of the cherubim being signified in. another form by the five pillars which sustain it.
