'Tablets of the Covenant' in the Bible

When I went up the mountain to receive the stone tablets, the tablets of the covenant the Lord made with you, I stayed on the mountain 40 days and 40 nights. I did not eat bread or drink water.

The Lord gave me the two stone tablets, the tablets of the covenant, at the end of the 40 days and 40 nights.

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

It contained the gold altar of incense and the ark of the covenant, covered with gold on all sides, in which there was a gold jar containing the manna, Aaron’s staff that budded, and the tablets of the covenant.
