'Double' in the Bible

And there was a woman who for eighteen years had had a sickness caused by a spirit; and she was bent double, and could not straighten up at all.

The elders who rule well are to be considered worthy of double honor, especially those who work hard at preaching and teaching.

Pay her back even as she has paid, and give back to her double according to her deeds; in the cup which she has mixed, mix twice as much for her.
