'One' in the Bible

I am grateful to the one who has strengthened me, Christ Jesus our Lord, because he considered me faithful in putting me into ministry,

For there is one God and one intermediary between God and humanity, Christ Jesus, himself human,

The overseer then must be above reproach, the husband of one wife, temperate, self-controlled, respectable, hospitable, an able teacher,

Deacons must be husbands of one wife and good managers of their children and their own households.

Let no one look down on you because you are young, but set an example for the believers in your speech, conduct, love, faithfulness, and purity.

But the one who lives for pleasure is dead even while she lives.

No widow should be put on the list unless she is at least sixty years old, was the wife of one husband,

and has a reputation for good works: as one who has raised children, practiced hospitality, washed the feet of the saints, helped those in distress -- as one who has exhibited all kinds of good works.
