ISB ~ Hebrews 9 v3

second curtain:The embroidered veil that hung as a partition between the Holy Place and the Holy of Holies (Ex 26:31-33). A similar veil separated the Holy Place from the outer courtyard.

Holy of Holies:The most sacred chamber of the Tabernacle, inaccessible to all but the high priest once a year (9:7). It housed the Ark of the Covenant, the golden chest that served as the earthly throne of Yahweh (Ex 25:10-15). The Ark was topped with the mercy seat and its two cherubim (Ex 25:17-22), and inside it were the tablets of the covenant (Ex 25:16), a jar of manna (Ex 16:33), and the rod of Aaron (Num 17:8-10).
