8:1–10:20 Section
Aaron and his sons Nadab and Abihu, Eleazar and Ithamar were set apart as priests.
God had given clear instructions about how to do this in Exodus chapters 28 and 29. The ceremony included washing with special water and putting on the priests’ clothes. It included being anointed with oil and being sprinkled with blood from the sacrifices.
After seven days, Aaron and his sons started their work as priests. God was very pleased that they obeyed him completely. God showed his glory to the whole community and sent fire upon the altar. This filled the people with joy.
The main work of priests was to offer sacrifices and to teach the people. They were to tell the difference between what was holy and what was common. But Nadab and Abihu didn’t do that. They made an offering that went against what God had commanded. Because of this the Lord sent fire that killed Nadab and Abihu.
