What does the Bible say about Christ as the High Priest?

Hebrews 5 describes Christ's role as High Priest, emphasizing that He was appointed by God, not by His own desire, to offer gifts and sacrifices for sins. Unlike the Levitical priests, who had to offer sacrifices for themselves as well, Christ was sinless and designated a priest forever in the order of Melchizedek. By fulfilling this role, He perfectly mediates between God and humanity, representing His chosen people in ways that previous priests could not, as He bore their names on His shoulders like Aaron did with the tribes of Israel in Exodus 28:10-12.
