Revelation 21:16 says, “he [an angel] measured the city [New Jerusalem] with the reed to a length of twelve thousand stadia; the length and the breadth and the height of it are equal.” The equal dimensions declare that New Jerusalem is a cube, and in the Bible a cube is the holy of holies (or holiest of all or most holy place).
The holy of holies in the tabernacle is first mentioned in Exodus 26:31-34; it was separated from the holy place by the veil. It contained the ark of the testimony with its expiation cover and two cherubim.
The ark was “the ark of the testimony” because the testimony was put into it (Ex. 25:16). Jesus Christ is the reality of the testimony; He is the one who testifies and displays all that God is. In the Old Testament picture the testimony was in the ark in the holy of holies; in the New Testament the testimony is in Jesus Christ who is the center of New Jerusalem, the eternal holy of holies.
The expiation cover of the ark was sprinkled with blood of offerings (Lev. 16:14-15). The Lord Jesus is the reality of these offerings (Heb. 10:5-10) for us now. He is also the Lamb on the throne in New Jerusalem (Rev. 22:1), our eternal Redeemer and Redemption.
Above the expiation cover were “the cherubim of glory” (Ex. 25:18-20, Heb. 9:5). This is another part of the holy of holies as a picture of New Jerusalem, the city of glory. Also, the gold of the ark, the expiation cover, and the cherubim all portray the gold of New Jerusalem (Rev. 21:18, 21).
The Lord said to Moses, “I will meet with you and I will speak with you” there—above the expiation cover and between the cherubim. This is a picture of God’s eternal meeting and speaking with His people in New Jerusalem.
