Ark: in the Tabernacle--Called the Ark of the Covenant: Pot of Manna

So Moses told Aaron, “Take a jar and fill it with an omer of manna. Then place it before the LORD to be preserved for the generations to come.”

And Aaron placed it in front of the Testimony, to be preserved just as the LORD had commanded Moses.

…containing the golden altar of incense and the gold-covered ark of the covenant. Inside the ark were the gold jar of manna, Aaron’s staff that had budded, and the stone tablets of the covenant.
