'Relation' in the Bible

Do not be false to the married relation.

One witness may not make a statement against a man in relation to any sin or wrongdoing which he has done: on the word of two or three witnesses a question is to be judged.

And if the wrongdoer is to undergo punishment by whipping, the judge will give orders for him to go down on his face and be whipped before him, the number of the blows being in relation to his crime.
