Exodus 35:5-19, 29

‘Take from among you an offering to the LORD. Whoever has a willing heart, let him bring it as the LORD’S offering: gold, silver, and bronze, blue, purple, and scarlet fabric, fine linen, goats’ hair, and rams’ skins dyed red, and skins of porpoises, and acacia wood, and [olive] oil for the lighting, and balsam for the anointing oil, and for the fragrant incense, and onyx stones and other stones to be set for the ephod and the breastpiece. ‘Let every skilled and talented man among you come, and make everything that the LORD has commanded: the tabernacle (sacred dwelling of God), its tent and its covering, its hooks, its boards, its bars, its pillars, and its sockets; the ark [of the covenant] and its carrying poles, with the mercy seat and the veil (partition curtain) of the screen [to hang between the Holy Place and the Holy of Holies]; the table and its carrying poles, and all its utensils, and the bread of the [divine] Presence (showbread); the lampstand also for the light and its utensils and its lamps, and the oil for the light; and the altar of incense and its carrying poles, the anointing oil and the fragrant incense, the screen (curtain) for the doorway at the entrance of the tabernacle; the altar of burnt offering with its bronze grating, its carrying poles, and all its utensils, the wash basin and its base (stand); the court’s curtains, its support poles and their sockets, and the curtain for the gate of the courtyard; the pegs of the tabernacle and the pegs of the court and their cords; the finely-woven garments for ministering in the Holy Place, the holy garments for Aaron the priest and the garments for his sons, to minister as priests.’ ”

The Israelites, all the men and women whose heart moved them to bring material for all the work which the LORD had commanded through Moses to be done, brought a freewill (voluntary) offering to the LORD.
