Deuteronomy 10:2-4

10:2 I will write on the tablets the same words that were on the first tablets you broke, and you must put them into the ark.” 10:3 So I made an ark of acacia wood and carved out two stone tablets just like the first ones. Then I went up the mountain with the two tablets in my hands. 10:4 The Lord then wrote on the tablets the same words, the ten commandments, which he had spoken to you at the mountain from the middle of the fire at the time of that assembly, and he gave them to me.
