God chooses to dwell with His people as they journey through the wilderness and the go to the Promised Land. They way God does is through he tabernacle and the priestly system. The tabernacle was a temporary dwelling designed by God. It was a large tent that could be dismantled, transported, and reassembled. Various names are given to the Tabernacle in the Scriptures: Sanctuary, Tent, Dwelling, and House. It was a symbolical picture of how a Holy God will dwell with a sinful people. The Lord was particular with regards to the tabernacle. We read, “ And let them make me a sanctuary, that I may dwell in their midst. Exactly as I show you concerning the pattern of the tabernacle, and of all its furniture, so you shall make it” (Exodus 25:8-9).
The tabernacle was to be located in a courtyard, which was 46m long and 23m wide. An outer linen curtain, which was about 2.3 m high, surrounded the courtyard. Only the priests could enter the courtyard and they were to offer sacrifices and maintain the tabernacle. In the inner courtyard was the Bronze Altar for sacrificing animals. These offerings were to be continually offered for the dwelling of God among the people (Ex. 29:42). Next to the altar was the Bronze Basin. This was for ceremonial washings. The priests would wash after an offering before they entered the tabernacle. Failing to do this could result in death (Ex. 30:21)
The actual Tabernacle was 13.5 M long, 4.5 M wide, 4.6 high. It was covered with curtains of blue, purple, and scarlet. They were covered with weather resistant goats hair, which was then covered with ram and badger skins. The tabernacle consisted of two rooms. The first room was the Holy Place. On the left was the lamp stand, which was to burn continually, and on the right was the table for the bread of His presence (12 loaves of bread). Straight ahead was the altar of incense, which would be burnt every morning and evening. The back wall was a curtain leading to the second room. This room was the most holy place, also known as the Holy of Holies. Only the High Priest could enter once a year (Leviticus 16). Inside that room was the Ark of the Covenant (Ex. 25:10-16). This object was 1.1 m long, 0.7 wide, and 0.7 high. Inside of it was the Ten Commandments, a pot of manna, and Aaron’s rod.
The tabernacle provided rich imagery pointing to the holiness of God, the sinfulness of man, and the grace of God. It demonstrated to the people how they could approach with God and abide with Him. Later on in the journey through the Bible we learn that this tabernacle is a picture of Jesus Christ. He came into the world and dwelt among us (John 1:14; the word “dwelt” in that verse is literally “pitched His tent”). In Hebrews 8-9 we learn with great clarity how the ministry of Jesus Christ actually accomplishes what the tabernacle in described in Exodus pointed to.
The priesthood was to participate (in accordance to the specific instruction of God) in the tabernacle and the sacrifices. The priest functioned as a mediator. He mediated between Israel and God and God and Israel. Aaron was the first High Priest and his sons were to be the priests. They were to wear special garments. These garments distinguished them from the other Israelites, and carried rich symbolic meaning. The High Priest was to wear different garments again. The priests were instructed by the Lord to follow carefully prescribed duties relating to the sacrificial system. The priesthood is discussed with great detail in Exodus 28:1-30:3.
