Exodus 34:1; Exodus 34:28

1 Now the LORD said to Moses, "Cut out for yourself two stone tablets like the former ones, and I will write on the tablets the words that were on the former tablets which you shattered.

28 So he was there with the LORD forty days and forty nights; he did not eat bread or drink water. And he wrote on the tablets the words of the covenant, the Ten Commandments.
