What does the Bible say about Jesus as our High Priest?

In Scripture, particularly in the book of Hebrews, Jesus is depicted as our great High Priest who fulfills the role in ways that surpass the Old Testament priests. He did not take the nature of angels but rather the seed of Abraham, making Him intimately familiar with human struggles and temptations (Hebrews 2:16-17). Unlike Aaron, who was merely a mortal, Jesus's divine nature ensures that His atonement is perfect and sufficient. As the only one who could bear the sins of His people without being stained by sin Himself, He accomplished what no other priest could do, thus establishing a new and everlasting covenant (Hebrews 10:12-18).
