Exodus 25:20-22

The cheruvim are to spread out their wings above, shielding the atonement cover with their wings, each facing its companion. The faces of the cheruvim are to be turned toward the atonement cover. You are to put the atonement cover on top of the Ark, and inside the Ark you will put the Testimony that I will give you. “I will meet with you there. I will speak with you from above the atonement cover—from between the two cheruvim that are on the Ark of the Testimony—about all that I will command you, for Bnei-Yisrael.
