'Serve' in the Bible

These men must first be tested; then if they are found to be blameless and beyond reproach [in their Christian lives], let them serve as deacons.

Those who have believing masters are not to be disrespectful toward them because they are brothers [in Christ], but they should serve them even better, because those who benefit from their kindly service are believers and beloved. Teach and urge these [duties and principles].
