Exodus 28-29 give lots of details of the proper attire (priestly garments & accessories) for Aaron and his sons as they serve the Lord as priests for the people. As 28:36 says, they are to be consecrated as "HOLY TO THE LORD" and to be anointed and ordained as ministers of the tabernacle according to all the ordinances given by God. God said, "So I will consecrate the Tent of Meeting and the alter and Aaron and his sons... then I will dwell among the Israelites and be their God... they will know that I am their God, who brought them out of Egypt so that I might dwell among them. I am the Lord their God."

Exodus 27 gives more details of the tabernacle, the alter for burnt offerings, the courtyard, and the lampstand. The alter for burnt offerings was the means for the people to come to God, since they hadn't yet benefited from the ultimate sacrifice of Jesus Christ for their sins. The Lampstand was to be kept burning constantly before the Lord.

In Exodus 25-26, the Lord instructed Moses with details how to have the people build a holy sanctuary where God would be able to live among them. Among the details, they were told to use pure gold for building much of the sanctuary and the furnishings ( table, lampstand, etc). There was much attention to precision and purity and God said "Be sure that you make everything according to the pattern I have shown you". The symbolism of perfection and purity in construction emphasized God's holiness.

In Exodus 24, after meeting with the Lord again, Moses recounted all the Lord's ordinances for the people and they responded "All that the Lord has spoken we will do, and we will be obedient!".

As Exodus 23 begins, God instructs His people in mercy and justice. He warns against favoritism, being a malicious witness, perverting justice by siding with the crowd, or denying justice with false charges. God reminds them that they were once oppressed in Egypt and were blessed by His mercy. God's laws of fairness were to be applied even to enemies. God told them He would send His angel to guide them, protect them, and give them further instruction, and go ahead of them and lead them to the promised land. God told them "if you listen carefully and do all that I say, I will be an enemy to your enemies and will oppose those who oppose you... and if you worship the Lord your God, His blessing will be on your food and water.. I will take away sickness from among you, none will miscarry or be barren in your land, and I will give you a full life span".

In Exodus 22, many examples are given of rules of responsibility , making it easier for the Israelites to discern God's will in different circumstances. God gave them these practical guidelines, " If a man ... , then he must...", because He says "You are to be my holy people" (v.31).

Exodus 21 introduces some laws regarding everyday life for the Israelites, so that they would understand that their actions had consequences. Judges were given the "eye for an eye" guideline so that punishments would fit the crimes.
