Deuteronomy 31:25

“Now it will be when he sits on the throne of his kingdom, that he shall write for himself a copy of this law on a scroll in the presence of the Levitical priests.

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

Then Hilkiah the high priest said to Shaphan the scribe, “I have found the book of the law in the house of Yahweh.” And Hilkiah gave the book to Shaphan and he read it.
