Kappōret identifies the gold cover associated with the ark, rendered mercy seat in the selected BSB passages. Exodus 25 specifies its construction and position, with cherubim above it and the Testimony placed inside the ark. The Lord appoints this location for meeting with Moses and speaking His commands concerning Israel. The noun therefore names a particular sanctuary object, not a general emotional state of mercy.
Leviticus 16 sets access within serious restrictions and prescribed atonement rites. Incense covers the mercy seat, and blood is applied there and before it for the sanctuary's cleansing from Israel's impurities and sins. Christian teaching may follow Hebrews 9 in relating the sanctuary arrangement to Christ's work, but that connection must come from the argument of Hebrews. The Hebrew noun by itself does not encode every later account of atonement or authorize free access on terms different from those stated in its passage.
