Hebrews 13:10-12

13:10 We have an altar that those who serve in the tabernacle have no right to eat from. 13:11 For the bodies of those animals whose blood the high priest brings ¹  into the sanctuary as an offering for sin are burned outside the camp. 13:12 Therefore, to sanctify the people by his own blood, Jesus also suffered outside the camp.

[13:11]  ¹ tn Grk “whose blood is brought by the high priest.”
