'Tablets of the Testimony' in the Bible

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

And Moses turned and went down from the mountain, and the two tablets of the testimony [were] in his hand, tablets written on their two sides; {on the front and on the back} they were written.

{And} when Moses came down from Mount Sinai, the two tablets of the testimony [were] in the hand of Moses at his coming down from the mountain; and Moses did not know that the skin of his face shone because of his speaking with him.
