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.
The LORD said: I promise to perform miracles for you that have never been seen anywhere on earth. Neighboring nations will stand in fear and know that I was the one who did these marvelous things.
Moses wrote down all of these laws and teachings and gave them to the priests and the leaders of Israel. The priests were from the Levi tribe, and they carried the sacred chest that belonged to the LORD.
The LORD said he was making an agreement with you, and he told you that your part of the agreement is to obey the Ten Commandments. Then the LORD wrote these Commandments on two flat stones.
