Mercy seat

The golden covering of the Ark of the Covenant in the Holy of Holies. It was the place of the manifestation of God's glory and his meeting place with his people (Ex. 25: 22; Lev. 16: 2; Num. 7: 89); and was regarded as the Throne of God (1 Sam. 4: 4; cf. Ex. 30: 6; Num. 7: 89). Here the blood of the sin offering was sprinkled on the day of Atonement (Lev. 16: 14-15).
