Malachi 2:13-15

New Catholic Bible

¹³ And this you are to do as well:
    you must cover the altar of the Lord
    with tears, with weeping and moaning,
because at present he refuses to consider your offering
    or to accept it with satisfaction from your hand.
¹⁴ If you ask the reason why,
    it is because the Lord stands as witness
    between you and the wife of your youth
with whom you have broken faith,
    even though she is your partner
    and your wife by a solemn covenant.
¹⁵ Did not the one God make her,
    both flesh and spirit?
And what does the one God require
    but God-given offspring?
Therefore, you must safeguard your own life,
    and let none of you be unfaithful
    to the wife of your youth.
