The Lord told Moses that he was to make two cherubim to sit on the Ark of the Testimony with the Mercy Seat in between.
Picture the sight of what the Lord said to Moses,
“Make one cherub at one end, and the other cherub at the other end; you shall make the cherubim at the two ends of it of one piece with the mercy seat. And the cherubim shall stretch out their wings above, covering the mercy seat with their wings, and they shall face one another; the faces of the cherubim shall be toward the mercy seat” (Exodus 25:19-20).
The Lord is all about mercy, otherwise, He would have ended humanity when Adam and Eve committed the first sins.
The way the cherubim flanked the Mercy Seat, facing it, and stretching out their wings over the Mercy Seat, showed further that this place, which was the heart of the tabernacle, emphasized the mercy of the Lord of heaven. He wanted to be merciful to Israel then, and He wants to be merciful to the world now. (See John 3:16; Romans 11:30–32; Romans 12:1; Romans 15:7.)
