'Lord's' in the Bible

Do not be indolent when zeal is required. Be thoroughly warm-hearted, the Lord's own servants,

Greetings to those Christian workers, Tryphaena and Tryphosa; also to dear Persis, who has laboured strenuously in the Lord's work.

Greetings to Rufus, who is one of the Lord's chosen people; and to his mother, who has also been a mother to me.
