'Set Apart' in the Bible

Therefore, holy brothers and sisters, who share in the heavenly calling, [thoughtfully and attentively] consider the Apostle and High Priest whom we confessed [as ours when we accepted Him as Savior], namely, Jesus;

For, such a high-priest as this, for us, was evensuited: Loving, noble, undefiled, set apart from sinners, and become, higher than the heavens;

For by one offering [i.e., the sacrifice of Himself], Christ has made perfect forever those people who are being set apart for God.

How much more severely do you think a person deserves to be punished who has trampled on the Son of God and has regarded the blood of the [New] Agreement, with which he was set apart for God, an unholy thing and has insulted the Holy Spirit, through whom God's unearned favor is shown?
