In the earthly ark Moses was required to place the tables of stone. These were called the tables of the testimony; and the ark was called the ark of the testimony, because they contained God’s testimony in the Ten Commandments. (SR 154.1) MC VC

Two Apartments VC

The tabernacle was composed of two apartments, separated by a curtain, or vail. All the furniture of the tabernacle was made of solid gold, or plated with gold. The curtains of the tabernacle were of a variety of colors, most beautifully arranged, and in these curtains were wrought, with threads of gold and silver, cherubim, which were to represent the angelic host, who are connected with the work of the heavenly sanctuary and who are ministering angels to the saints upon the earth. (SR 154.2) MC VC

Within the second vail was placed the ark of the testimony, and the beautiful and rich curtain was drawn before the sacred ark. This curtain did not reach to the top of the building. The glory of God, which was above the mercy seat, could be seen from both apartments, but in a much less degree from the first apartment. (SR 154.3) MC VC

Directly before the ark, but separated by the curtain, was the golden altar of incense. The fire upon this altar was kindled by the Lord Himself, and was sacredly cherished by feeding it with holy incense, which filled the sanctuary with its fragrant cloud day and night. Its fragrance extended for miles around the tabernacle. When the priest offered the incense before the Lord he looked to the mercy seat. Although he could not see it he knew it was there, and as the incense arose like a cloud, the glory of the Lord descended upon the mercy seat and filled the most holy place and was visible in the holy place, and the glory often so filled both apartments that the priest was unable to officiate and was obliged to stand at the door of the tabernacle.
