Deuteronomy 10:2-4

2I will write on the tablets the words that were on the first tablets, which you broke. Then you are to put them in the ark.” 3So I made the ark out of acacia wood and chiseled out two stone tablets like the first ones, and I went up on the mountain with the two tablets in my hands. 4The Lord wrote on these tablets what he had written before, the Ten Commandments he had proclaimed to you on the mountain, out of the fire, on the day of the assembly. And the Lord gave them to me.
