Propitiatory

Watson's Biblical & Theological Dictionary

among the Jews, was the cover or lid of the ark of the covenant, which was lined both within and without with plates of gold, insomuch that there, was no wood to be seen. Some even take it to have been one piece of massive gold. The cherubims spread their wings over the propitiatory. This propitiatory was a type or figure of Christ. See Propitiation .
