Greetings! This reading is Leviticus 10-12.
This section gets off to a sobering beginning:
Leviticus 10:1-3 Aaron’s sons Nadab and Abihu took their censers, put fire in them and added incense; and they offered unauthorized fire before the Lord, contrary to his command. So fire came out from the presence of the Lord and consumed them, and they died before the Lord. Moses then said to Aaron, “This is what the Lord spoke of when he said: “‘Among those who approach me I will show myself holy; in the sight of all the people I will be honored.’” Aaron remained silent.
It is not specified exactly what made the fire unauthorized, but it was obviously something serious.
Trivia fact: The only recorded instance of God speaking directly to Aaron is in verses 8-11. The priests were not to drink any alcohol. This appears to be able to help them distinguish between what is and isn’t holy.
Leviticus 10:8-11 Then the Lord said to Aaron, “You and your sons are not to drink wine or other fermented drink whenever you go into the Tent of Meeting, or you will die. This is a lasting ordinance for the generations to come. You must distinguish between the holy and the common, between the unclean and the clean, and you must teach the Israelites all the decrees the Lord has given them through Moses.”
Chapter 11 covers clean and unclean foods. This is a good example of how God made ceremonial laws just for the Israelites to set them apart from other nations. God communicates that these laws have been fulfilled through Christ in Acts 10.
Chapter 12 is a short section on purification after childbirth. I am not sure (and neither were two study Bibles I consulted) why the the woman had to wait longer after having a female than with a male. One did point out that while God is obviously pro-children, the rules for worship kept sex out of it (unlike many fertility cults and other false religions).
Note that in Luke 2:22-24 Mary and Joseph couldn’t afford a lamb, so they offered a pair of birds.
