Exodus 40:26-38

He put the golden altar [of incense] in the Tent of Meeting in front of the veil; he burned fragrant incense [as a symbol of prayer] on it, just as the LORD commanded him. [Ps 141:2; Rev 8:3] Then he set up the screen (curtain) at the doorway of the tabernacle. He set the altar of burnt offering before the doorway of the tabernacle of the Tent of Meeting, and offered on it the burnt offering and the grain offering, just as the LORD commanded him. He placed the basin between the Tent of Meeting and the altar [of burnt offering], and put water in it for washing. Then from it Moses and Aaron and his sons washed their hands and their feet. When they entered the Tent of Meeting, and when they approached the altar, they washed, just as the LORD commanded Moses. And he erected the courtyard all around the tabernacle and the altar, and hung the screen (curtain) at the gateway of the courtyard. So Moses finished the work. ORD Then the cloud [the Shekinah, God’s visible, dwelling presence] covered the Tent of Meeting, and the glory and brilliance of the LORD filled the tabernacle. [Rev 15:8] Moses was not able to enter the Tent of Meeting because the cloud remained on it, and the glory and brilliance of the LORD filled the tabernacle. In all their journeys, whenever the cloud was taken up from over the tabernacle, the Israelites would set out; but if the cloud was not taken up, then they did not journey on until the day when it was taken up. For throughout all their journeys, the cloud of the LORD was on the tabernacle by day, and there was fire in it by night, in the sight of all the house of Israel.
