After telling us that the chiefs of the twelve tribes each offered a silver bowl and basin and golden ladle to the Tabernacle, the Torah adds: This is the dedication offering of the altar on the day of its anointing from the chieftains of Israel: twelve silver bowls, twelve silver basins, twelve golden ladles…(Numbers 7:84) This verse is superfluous for obviously there were twelve of each item. Maharal explains that the chiefs were not required to bring anything at all. The Torah is teaching us that although these items were never requested, nonetheless at the dedication of the altar they were all present. When we give a gift, we want to know that the gift will be put to good use, and so the Torah not only tells us what the chiefs donated but also highlights how they were used at the dedication of the Tabernacle.
