4 Then Moses wrote down what the Lord had said.The next morning Moses got up early. He built an altar at the foot of the mountain and set up a large stone for each of the twelve tribes of Israel.
5 He also sent some young men to burn offerings and to sacrifice bulls as special offerings to the Lord.
6 Moses put half of the blood from the animals into bowls and sprinkled the rest on the altar.
7 Then he read aloud the Lord's commands and promises, and the people shouted, “We will obey the Lord and do everything he has commanded!”
8 Moses took the blood from the bowls and sprinkled it on the people. Next, he told them, “With this blood the Lord makes his agreement with you.”
9 Moses and Aaron, together with Nadab and Abihu and the seventy leaders, went up the mountain
10 and saw the God of Israel. Under his feet was something that looked like a pavement made out of sapphire, and it was as bright as the sky.
