Hebrews 13:11

Far from defiling those who associated with Jesus Christ, our sin (purification) offering, associating with Him leads to holiness. Here the writer compared Jesus to the sin offering that the Jewish high priest offered on the Day of Atonement (cf. Leviticus 16:27).

". . . in Hebrews the expression ’high priest’ customarily signals that the field of reference is the annual atonement ritual (cf. Hebrews 5:3; Hebrews 7:27; Hebrews 8:1-3; Hebrews 9:7; Hebrews 9:11-12; Hebrews 9:24-26)." [Note: Lane, Hebrews 9-13, p. 540.]
