Exodus 22 - 24
In chapters 22-23 God continues in giving Moses the commandments of His law.
In chapter 24 Moses writes down, and recounts to the people all of God’s laws, and they swear to obey them all. God appears in glory to Moses and the 70 elders, which would have been a pre-incarnate appearance of Jesus (see also Isaiah 6), and then Moses is called up to the top of the mountain to meet with God for 40 days.
