'Tablets of Stone' in the Bible

He gave Moses two tablets of testimony when he had finished speaking with him on Mount Sinai, tablets of stone written by the finger of God.

The Lord said to Moses, "Cut out two tablets of stone like the first, and I will write on the tablets the words that were on the first tablets, which you smashed.

So Moses cut out two tablets of stone like the first; early in the morning he went up to Mount Sinai, just as the Lord had commanded him, and he took in his hand the two tablets of stone.
