What does the Bible say about the anointing of Aaron?

Psalm 133:2 illustrates the anointing of Aaron, the first Jewish high priest, which serves as a type or shadow of the anointing of Jesus Christ, our eternal High Priest. This passage reveals how the precious ointment represented the fullness of the Holy Spirit given to Christ without measure. Just as the anointing oil flowed from Aaron's head down to his garments, symbolizing the blessings of God extending to the people, Jesus, in His role as the Sun of Righteousness, imparts His grace and fullness to all His followers. The Apostle Paul affirms this by stating that it pleased the Father for all fullness to dwell in Christ, from whom we receive grace upon grace.
