“Go back down the mountain and tell the people that if they obey me, they will be my treasure.” God told Moses. So Moses went back down the Mountain and told the people what God had said.
“We will surely do whatever God commands.” Agreed all the people. Moses went back up the mountain to relay the message to God (although God knows and hears everything anyway). Moses is over eighty years old by now, so going up and down the mountain is not so easy for him.
When Moses reached the place where he met God, God said. “ I want the people to hear me talk to you so that they will respect you more. Go back down and tell the people that in three days I will speak to you. But I want them to hear me. When a loud trumpet blasts, have them come close to the bottom of the mountain, but make a boundary there. Tell them that no one is to cross that boundary or they will die.” So Moses went back down the mountain and told the people what God had said.
On the third day, the people made sure they had on their best clean clothes. After all, they were going to hear directly from God today! While they were eating breakfast, they were startled by the sound of a loud trumpet blast. They all went to the base of the mountain where Moses had set up a boundary. As the people gathered, Moses went back up the mountain. The top of the mountain was covered in dark smoke. When Moses reached the smoke, God spoke. “Go back down and tell the people not to cross the boundary or they will die.”
"But I already told them.” Moses said. “They know about the boundary.”
Moses went back down the mountain. I’m sure he was getting very tired of going up and down that mountain. He reminded the people about the boundary and then told Aaron to come with him back up the mountain. About half way up, Moses told Aaron to wait there and Moses went up into the smoke covered mountaintop. Thunder boomed and lightning flashed! The mountain shook! God began to speak! 2 million Hebrews heard God speak that day as he began telling them the ten commandments. Did you know that God spoke the ten commandments before He wrote them on the stone tablets? The Hebrews were very afraid. They began to move back toward their camp. Moses called down to the people not to be afraid, but they kept on going back to camp. Moses remained on the mountain. God continued to speak to Moses.
