'Wife' in the Bible

And ye have said, 'Wherefore?' Because Jehovah hath testified between thee And the wife of thy youth, That thou hast dealt treacherously against her, And she thy companion, and thy covenant-wife.

And He did not make one only, And He hath the remnant of the Spirit. And what is the one alone! He is seeking a godly seed. And ye have been watchful over your spirit, And with the wife of thy youth, None doth deal treacherously.
