Deuteronomy 10:3-5

3So I made an ark of acacia wood and cut out two tablets of stone like the first, and went up the mountain with the two tablets in my hand.

4The Lord wrote on the tablets, like the first writing, the Ten Commandments which the Lord had spoken to you on the mountain from the midst of the fire on the day of the assembly; then the Lord gave them to me.

5Then I turned and came down from the mountain and put the tablets in the ark which I had made; and they are there, just as the Lord commanded me.”
