Exodus 24:3-4

New Living Translation

³ Then Moses went down to the people and repeated all the instructions and regulations the Lord had given him. All the people answered with one voice, “We will do everything the Lord has commanded.”

⁴ Then Moses carefully wrote down all the Lord’s instructions. Early the next morning Moses got up and built an altar at the foot of the mountain. He also set up twelve pillars, one for each of the twelve tribes of Israel.
