'Set apart' in the Bible

While they were engaged in the worship of the Lord and were fasting, the Holy Spirit said: "Set apart for me Barnabas and Saul, for the work to which I have called them."

To all in Rome who are dear to God and have been called to become Christ's People, From Paul, a servant of Jesus Christ, who has been called to become an Apostle, and has been set apart to tell God's Good News.

If, then, a man has escaped from the pollution of such errors as I have mentioned, he will be like a thing kept for better use, set apart, serviceable to its owner, ready for any good purpose.
