2. Speak unto Aaron, &c.--The candlestick, which was made of one solid, massive piece of pure gold, with six lamps supported on as many branches, a seventh in the center surmounting the shaft itself (Ex 25:31; 37:17), and completed according to the pattern shown in the mount, was now to be lighted, when the other things in the sanctuary began to be applied to religious service. It was Aaron's personal duty, as the servant of God, to light His house, which, being without windows, required the aid of lights (2Pe 1:19). And the course he was ordered to follow was first to light the middle lamp from the altar-fire, and then the other lamps from each other--a course symbolical of all the light of heavenly truth being derived from Christ, and diffused by His ministers throughout the world (Re 4:5).
      the seven lamps shall give light over against the candlestick--The candlestick stood close to the boards of the sanctuary, on the south side, in full view of the table of showbread on the north (Ex 26:35), having one set of its lamps turned towards the east, and another towards the west; so that all parts of the tabernacle were thus lighted up.
