'Tablets of the Covenant' in the Bible

When I went up the mountain to receive the stone tablets, the tablets of the covenant that the Lord made with you, I remained there forty days and nights, eating and drinking nothing.

Now at the end of the forty days and nights the Lord presented me with the two stone tablets, the tablets of the covenant.

So I turned and went down the mountain while it was blazing with fire; the two tablets of the covenant were in my hands.

It contained the golden altar of incense and the ark of the covenant covered entirely with gold. In this ark were the golden urn containing the manna, Aaron's rod that budded, and the stone tablets of the covenant.
