What does the Bible say about the high priest's blessing?

The high priest's blessing is a significant biblical concept that connects to the atonement made for the people of Israel. In Luke 24:50-53, we see Christ lift His hands and bless the disciples as He ascends to heaven. This act is reflective of the Old Testament practice where the high priest, after performing the sacrificial duties, would bless the people. It symbolizes not only the acceptance of the atonement but also the grace of God upon His chosen ones who are in Christ. As believers, we understand this blessing is fulfilled in Christ, the Great High Priest, who offered Himself as the ultimate sacrifice for sin and now intercedes for us from heaven.
