Hebrews 9:7

9:7 But only the high priest enters once a year into the inner tent, ¹  and not without blood that he offers for himself and for the sins of the people committed in ignorance. ² 

Hebrews 11:28

11:28 By faith he kept the Passover and the sprinkling of the blood, ³  so that the one who destroyed the firstborn would not touch them.

[9:7]  ¹ tn Grk “the second tent.”

[9:7]  ² tn Or perhaps “the unintentional sins of the people”; Grk “the ignorances of the people.” Cf. BDAG 13 s.v. ἀγνόημα, “sin committed in ignorance/unintentionally.” This term seems to be simply a synonym for “sins” (cf. Heb 5:2) and does not pick up the distinction made in Num 15:22-31 between unwitting sin and “high-handed” sin. The Day of Atonement ritual in Lev 16 covered all the sins of the people, not just the unwitting ones.

[11:28]  ³ tn Grk “the pouring out of the blood.”
