Exodus 30:16

Thou shalt... appoint it for the service of the tabernacle. — It appears, by Exodus 38:27, that the silver collected by this tax, which amounted to above a hundred talents, was employed for making the sockets which supported the boards of the tabernacle (Exodus 26:19), and those of the pillars of the vail (Exodus 26:32), together with the hooks for the pillars of the court, their capitals, and connecting rods. Thus, so long as the tabernacle stood, the precious metal paid as ransom remained in the sight of the people, and was a continual “memorial,” or reminder, to them of the position into which they were brought by covenant with God.
