'Serving' in the Bible

They were to be young men without physical defect, handsome in appearance, skilled in all wisdom, quick to learn, prudent in how they used knowledge, and capable of serving in the king's palace. They were to learn the literature and language of the Chaldeans.

A river of fire flowed out from before him. Thousands upon thousands were serving him, with millions upon millions waiting before him. The court sat in judgment, and record books were unsealed.
