The ark of the covenant was to be constucted in just such a way (Exodus 25:10-22). The lid atop this gold covered wooden box was to be of solid gold with two cherubs (one on either end). The lid is referred to as the mercy seat.
Exodus 25:22 And there I will meet with thee, and I will commune with thee from above the mercy seat, from between the two cherubims which are upon the ark of the testimony, of all things which I will give thee in commandment unto the children of Israel.
Now notice:
John 20:11 But Mary stood without at the sepulchre weeping: and as she wept, she stooped down, and looked into the sepulchre, 12 And seeth two angels in white sitting, the one at the head, and the other at the feet, where the body of Jesus had lain. 13 And they say unto her, Woman, why weepest thou? She saith unto them, Because they have taken away my Lord, and I know not where they have laid him.

The Mercy Seat atop the ark of the covenant was a prophetic depiction of the slab in the empty tomb where Jesus body had lain in death but was raised from the death unto eternal life.
