These chapters largely mirror chapters 26-30. Everything the Lord told them to do, they did. Exodus is taking a lot of space to make a very powerful point: follow God, follow His instructions, don’t waver to the left or right. This is an important point, and something we will either learn from listening to God, or through the pain that comes when I go my own way.
