Hebrews 12:27

12:27 Now this phrase “once more” indicates the removal of what is shaken, that is, of created things, so that what is unshaken may remain.

Hebrews 9:8

9:8 The Holy Spirit is making clear that the way into the holy place had not yet appeared as long as the old tabernacle ¹  was standing.

[9:8]  ¹ tn Grk “the first tent.” The literal phrase “the first tent” refers to either (1) the outer chamber of the tabernacle in the wilderness (as in vv. 2, 6) or (2) the entire tabernacle as a symbol of the OT system of approaching God. The second is more likely given the contrast that follows in vv. 11-12.
