Exodus 40:24-28

Then he put the lampstand in the Tent of Meeting, opposite the table, on the south side of the tabernacle. Moses mounted and lighted the lamps [on the lampstand] before the LORD, just as the LORD commanded him. 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.
