Hebrews 9:3

9:3 And after the second curtain there was a tent called the holy of holies.

Hebrews 6:19

6:19 We have this hope as an anchor for the soul, sure and steadfast, which reaches inside behind the curtain,

Hebrews 10:20

10:20 by the fresh and living way that he inaugurated for us through the curtain, that is, through his flesh,

sn The curtain refers to the veil or drape in the temple that separated the holy place from the holy of holies.

tn Grk “that he inaugurated for us as a fresh and living way,” referring to the entrance mentioned in v. 19.

sn Through his flesh. In a bold shift the writer changes from a spatial phrase (Christ opened the way through the curtain into the inner sanctuary) to an instrumental phrase (he did this through [by means of] his flesh in his sacrifice of himself), associating the two in an allusion to the splitting of the curtain in the temple from top to bottom (Matt 27:51; Mark 15:38; Luke 23:45). Just as the curtain was split, so Christ’s body was broken for us, to give us access into God’s presence.
