Tabernacle of Testimony
“And after that I looked, and, behold, the temple of the tabernacle of the testimony in heaven was opened:” (Rev 15:5 KJV)
This is the Temple in Heaven that was seen in chapter 11:
“And the temple of God was opened in heaven, and there was seen in his temple the ark of his testament: and there were lightnings, and voices, and thunderings, and an earthquake, and great hail.” (Rev 11:19 KJV)
The temple in Heaven contains the Tabernacle of Testimony. Another word for testimony is witness. The testimony is the contract, or witness, that God made with His people. Since the temple contains the ark of His testament, it is possible this testimony could be the Ten Commandments.
