He made the candlestick - See this described in the note on Exodus 25:31 (note).

And he made the candlestick of pure gold: of beaten work made he the candlestick; his shaft, and his branch, his bowls, his knops, and his flowers, were of the same:

37:17 This candlestick, which was not of wood overlaid with gold, but all beaten - work of pure gold only, signified that light of divine revelation with which God's church upon earth (which is his tabernacle among men) hath always been enlightened, being always supplied with fresh oil from Christ the good olive, Zech 4:2,3. The bible is a golden candlestick, it is of pure gold; from it light is diffused to every part of God's tabernacle, that by it the spiritual priests may see to do the service of his sanctuary. The candlestick has not only its bowls for necessary use, but its knops and flowers for ornament; many things which God saw fit to beautify his word with, which we can no more give a reason for than for these knops and flowers, and yet must be sure they wert added for good purpose. Let us bless God for this candlestick, have an eye to it continually, and dread the removal of it out of its place!

17-22. he made the candlestick of pure gold-Practical readers will be apt to say, "Why do such works with the hammer, when they could have been cast so much easier-a process they were well acquainted with?" The only answer that can be given is, that it was done according to order. We have no doubt but there were reasons for so distinctive an order, something significant, which has not been revealed to us [Napier]. The whole of that sacred building was arranged with a view to inculcate through every part of its apparatus the great fundamental principles of revelation. Every object was symbolical of important truth-every piece of furniture was made the hieroglyphic of a doctrine or a duty-on the floor and along the sides of that movable edifice was exhibited, by emblematic signs addressed to the eye, the whole remedial scheme of the gospel. How far this spiritual instruction was received by every successive generation of the Israelites, it may not be easy to determine. But the tabernacle, like the law of which it was a part, was a schoolmaster to Christ [Ga 3:24, 25]. Just as the walls of schools are seen studded with pictorial figures, by which the children, in a manner level to their capacities and suited to arrest their volatile minds, are kept in constant and familiar remembrance of the lessons of piety and virtue, so the tabernacle was intended by its furniture and all its arrangements to serve as a "shadow of good things to come" [Heb 10:1]. In this view, the minute description given in this chapter respecting the ark and mercy seat, the table of showbread, the candlestick, the altar of incense, and the holy oil, were of the greatest utility and importance; and though there are a few things that are merely ornamental appendages, such as the knops and the flowers, yet, in introducing these into the tabernacle, God displayed the same wisdom and goodness as He has done by introducing real flowers into the kingdom of nature to engage and gratify the eye of man.

37:1-29 The making of the ark, and the furniture of the tabernacle. - In the furniture of the tabernacle were emblems of a spiritual and acceptable service. The incense represented the prayers of the saints. The sacrifice of the alter represented the Lamb of God that taketh away the sins of the world. The golden pot with manna, or bread from heaven, the flesh of Jesus Christ, which he gave for the life of the world. The candlestick, with its lights, the teaching and enlightening of the Holy Spirit. The shew-bread represented that provision for those who hunger and thirst after righteousness, which the gospel, the ordinances and the sacraments of the house of prayer, abundantly bestow. The exactness of the workmen to their rule, should be followed by us; seeking for the influences of the Holy Spirit, that we may rejoice in and glorify God while in this world, and at length be with him for ever.
