18 “You must not offer the blood of my sacrifice with bread containing yeast; the fat of my festal sacrifice must not remain until morning. 19 The first of the firstfruits of your soil you must bring to the house of the Lord your God. “You must not cook a young goat in its mother’s milk. 20 “I am going to send a messenger before you to protect you as you journey and to bring you into the place that I have prepared. 21 Take heed because of him, and obey his voice; do not rebel against him, for he will not pardon your transgressions, for my Name is in him. 22 But if you diligently obey him and do all that I command, then I will be an enemy to your enemies, and I will be an adversary to your adversaries.

1 “Behold^*, 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 of Heaven’s Armies. 2 Who can endure the day of his coming? Who can keep standing when he appears? For he will be like a refiner’s fire, like a launderer’s soap. 3 He will act like a refiner and purifier of silver and will cleanse the Levites and refine them like gold and silver. Then they will offer the Lord a proper offering.
