Chapter 16: In the start of this chapter some people from the community were trying to oppose Moses and when he heard this he fell. Moses told each man to present the censor to the lord. The people who were opposed to Moses where either consumed by fire or eating by the ground.
Chapter 17: In this chapter God told Moses to gather the twelve staffs of Israel so that his people wont rebel against him. In the end the people of Israel started talking strange things.
Chapter 19: This chapter talks about what people should do in certain circumstances. One example is when people die in a tent you should not enter a tent will be unclean for 7 days.
Reflection: Overall these chapters are about how the Israelites rebelled against Moses and that was a bad thing to do. Chapter 19 is about laws that are very specific about what you should do.
