Israel brings offerings for an initial sacrifice to God. Each tribe brought:
1 silver plate, with flour and oil
1 silver basin, with flour and oil
1 gold dish, with incense
1 bull, 1 ram, 1 lamb for burnt offering
1 goat for sin offering
2 oxen, 5 rams, 5 goats, 5 lambs for peace offering
They also brought it in carts with oxen, for the Levites to have and use.
Moses would go into the holy of holies, and heard God's voice from above the ark, giving instructions.
7 lamps are set up before the main lampstand.
Levites sprinkled with water, shaved, and an offering made for them, to consecrate them to serve in the tabernacle. They were to work there from age 25 to 50.
How this is about Jesus
Jesus appoints helpers in His house (Ephesians 4:11-13) and we bring Him a sacrifice of praise (Hebrews 13:15).
We do not hear His voice audibly anymore, but have it more confirmed in the apostles' word written in the Bible (2 Peter 1:16-21).
Sins this may reveal
We are slow or reluctant to give to God or to support those serving His church or mission.
