Malachi 2:15

2:15 No one who has even a small portion of the Spirit in him does this. What did our ancestor do when seeking a child from God? Be attentive, then, to your own spirit, for one should not be disloyal to the wife he took in his youth.

Malachi 3:1

3:1 “I am about to send my messenger, who will clear the way before me. Indeed, the Lord you are seeking will suddenly come to his temple, and the messenger of the covenant, whom you long for, is certainly coming,” says the Lord who rules over all.
