Chapter seven is the longest chapter in Numbers by far. It goes back in time to when Moses first assembled the tabernacle and the priests dedicated it (Exodus 40). Numbers 7:1-9 gives an additional piece of information about the transportation of the tabernacle. Although the furniture pieces were carried by their poles, the frame structure, curtains, ropes, etc. were all pulled in ox-drawn carts, which were contributed by the other tribes. Along with these carts, each tribe gave a significant contribution to the Levites, one each day for twelve days (Numbers 7:12-82):
one silver platter weighing 130 shekels, and one silver sprinkling bowl weighing 70 shekels, both according to the sanctuary shekel, each of them full of fine flour mixed with olive oil as a grain offering; one gold pan weighing 10 shekels, full of incense; one young bull, one ram, and one male lamb in its first year, for a burnt offering; one male goat for a purification offering; and for the sacrifice of peace offerings: two bulls, five rams, five male goats, and five male lambs in their first year. (Numbers 7:13-17)
For the next week-and-a-half, the other tribes contributed exactly the same gifts. Together these made the dedication of the tabernacle a magnificent celebration. Once this procession was completed, and Moses had officially accepted the gifts, he entered the tabernacle, and God spoke to him (Numbers 7:89).
