32So all the work for the tabernacle, the Tent of Meeting, was completed. The Israelites did everything just as the LORD had commanded Moses. 33Then they brought the tabernacle to Moses: 34the covering of ram skins dyed red, the covering of fine leather, and the veil of the covering; 35the ark of the Testimony with its poles and the mercy seat; 36the table with all its utensils and the Bread of the Presence; 37the pure gold lampstand with its row of lamps and all its utensils, as well as the oil for the light; 38the gold altar, the anointing oil, the fragrant incense, and the curtain for the entrance to the tent; 39the bronze altar with its bronze grating, its poles, and all its utensils; 40the curtains of the courtyard with its posts and bases; 41and the woven garments for ministering in the sanctuary, both the holy garments for Aaron the priest and the garments for his sons to serve as priests. 42The Israelites had done all the work just as the LORD had commanded Moses. 43And Moses inspected all the work and saw that they had accomplished it just as the LORD had commanded. So Moses blessed them.
