'Ministering' in the Bible

As they were ministering to the Lord and fasting, the Holy Spirit said, “Set apart for Me Barnabas and Saul for the work I have called them to.”

and having sent to Macedonia two of those ministering to him -- Timotheus and Erastus -- he himself stayed a time in Asia.

Then he gave orders to the centurion for him to be kept in custody and yet have some freedom, and not to prevent any of his friends from ministering to him.
