'Separated' in the Bible

But to the married I enjoin, not I, but the Lord, Let not wife be separated from husband;

(but if also she shall have been separated, let her remain unmarried, or be reconciled to her husband;) and let not husband leave wife.

For the unbelieving husband is sanctified [that is, he receives the blessings granted] through his [Christian] wife, and the unbelieving wife is sanctified through her believing husband. Otherwise your children would be [ceremonially] unclean, but as it is they are holy.

and his interests are divided. The unmarried woman or the virgin is concerned about the matters of the Lord, how to be holy and set apart both in body and in spirit; but a married woman is concerned about worldly things, how she may please her husband.
