'Stewards' in the Bible

Let a man so account of us, as of the ministers of Christ, and stewards of the mysteries of God.

Moreover it is required in stewards, that a man be found faithful.

Instead, he is under guardians and stewards until the time set by his father.

As every man hath received the gift, even so minister the same one to another, as good stewards of the manifold grace of God.
