Mercy-seat @ (Heb. kapporeth, a "covering;" LXX. and N.T., hilasterion; Vulg., propitiatorium), the covering or lid of the ark of the covenant (q.v.). It was of acacia wood, overlaid with gold, or perhaps rather a plate of solid gold, 2 1/2 cubits long and 1 1/2 broad Exodus:25:17Exodus:30:6Exodus:31:7 ). It is compared to the throne of grace Hebrews:9:5; Ephesians:2:6). The holy of holies is called the "place of the mercy-seat" ( 1Chronicles:28:11: Leviticus:16:2). It has been conjectured that the censer (thumiaterion, meaning "anything having regard to or employed in the burning of incense") mentioned in Hebrews:9:4 was the "mercy-seat," at which the incense was burned by the high priest on the great day of atonement, and upon or toward which the blood of the goat was sprinkled Leviticus:16:11-16; comp. Numbers:7:89 and Exodus:25:22).
