God promised, “I am sending an angel before you,” to guard Israel on the way and bring them to a prepared place. Moses warned the people to listen and not to bow to the gods of the land. They were to tear down idols and smash pillars. God said the nations would be driven out little by little, so the land would not become empty and wild animals multiply.
Then Moses was told to come up with Aaron, Nadab, Abihu, and seventy elders, while the people stayed below. Moses repeated all God’s commands, and everyone answered together, “All that God has commanded we will do!” He wrote the words down, built an altar with twelve pillars for the tribes, and offered burnt offerings and well-being offerings. He read the covenant aloud, and the people promised again. Moses dashed blood on the altar and on the people, calling it the blood of the covenant.
Moses and the leaders went up and saw the God of Israel, with something like sapphire pavement beneath His feet. Afterward Moses climbed higher with Joshua. A cloud covered the mountain; on the seventh day Moses was called into it. The Presence of God looked like a consuming fire, and Moses remained on the mountain forty days and forty nights.
