TSK · Exodus 34:27

Moses wrote all the words of Yahweh, and rose up early in the morning, and built an altar under the mountain, and twelve pillars for the twelve tribes of Israel.

He said, "Behold, I make a covenant: before all your people I will do marvels, such as have not been worked in all the earth, nor in any nation; and all the people among which you are shall see the work of Yahweh; for it is an awesome thing that I do with you.

Moses wrote this law, and delivered it to the priests the sons of Levi, who bore the ark of the covenant of Yahweh, and to all the elders of Israel.
