Malachi 2:13-16

And this have ye done again, covering the altar of the Lord with tears, with weeping, and with crying out, insomuch that he regardeth not the offering any more, or receiveth it with good will at your hand. Yet ye say, Wherefore? Because the Lord hath been witness between thee and the wife of thy youth, against whom thou hast dealt treacherously: yet is she thy companion, and the wife of thy covenant. And did not he make one? Yet had he the residue of the spirit. And wherefore one? That he might seek a godly seed. Therefore take heed to your spirit, and let none deal treacherously against the wife of his youth. For the Lord, the God of Israel, saith that he hateth putting away: for one covereth violence with his garment, saith the Lord of hosts: therefore take heed to your spirit, that ye deal not treacherously.

Malachi 1:6-7

A son honoureth his father, and a servant his master: if then I be a father, where is mine honour? and if I be a master, where is my fear? saith the Lord of hosts unto you, O priests, that despise my name. And ye say, Wherein have we despised thy name? Ye offer polluted bread upon mine altar; and ye say, Wherein have we polluted thee? In that ye say, The table of the Lord is contemptible.
