Chapter 17

As we read in the previous chapter, the Israelites complained about not having enough to eat, so God gave them manna from heaven. This time, they’re whining that they don’t enough water to drink. Moses is afraid that they’re going to stone him to death, so God commands him to take his staff and hit the Rock of Horeb and water will come out of it. So he does it and sure enough, water came forth. The Israelites quarreled and tested the Lord and wondered if he was with them.
Then we get the story where Amalek came and fought with Israel. So Joshua was told to choose some men to go out and fight while Moses, Aaron, and Hur went up on the hill and as long as Moses raised his arms, the Israelites would be winning, but if his arms dropped, then Amalek would start winning. Eventually, Moses got tired, and so Aaron and Hur each held up an arm, which to me sounds like cheating.
14Then the LORD said to Moses, “Write this as a reminder in a book and recite it in the hearing of Joshua: I will utterly blot out the remembrance of Amalek from under heaven.”

If you write down a person’s name in a book that you intend to blot out of remembrance, are you actually doing just that? This makes no sense.
Chapter 18

So apparently Moses sent his wife and kids back to her father, Jethro (pictured), but now sent word that he was coming to see him and bringing his wife and kids. They met up, Moses told him all that had happened, and they made burnt offerings, and ate bread.
The next day, Moses sat as judge for the people to settle their disputes, but Jethro convinced him to created a municipal court system where judges would be appointed to settle lesser disputes. That’s it. That’s the chapter. It’s a lot of words for not a lot of substance.
Chapter 19

After three months, the Israelites came to Mount Sinai and the Lord told Moses to tell the people, paraphrasing here, “obey God.” God also tells Moses that he will appear as a dense cloud so that the people could hear what Moses is being told so that they will trust him.
So God tells Moses to tell the people not to go up the mountain or even touch the edge of it or else they will be stoned (not in the good way) or shot with arrows (also, not in the good way). They were to wash their clothes and prepare for the third day, and not go near a woman. Of course, if the person in question is a woman, that would be difficult to do.
God appeared as a pillar of smoke and descended on the mountain as he said would and Moses introduced Israel to God. Then God summoned him up the mountain and told him to go down and tell the people to stay off the mountain. Moses had to be in spectacular shape from going up and down the mountain so many times. Moses was told to go down the mountain and bring Aaron up, again, telling the people not to come up.
