New American Standard Bible (NASB)
Malachi 1
12 "But you are profaning it, in that you say, ’The table of the Lord is defiled, and as for its fruit, its food is to be despised.’
13 You also say, ’My, how tiresome it is!’ And you disdainfully sniff at it," says the Lord of hosts, "and you bring what was taken by robbery and what is lame or sick; so you bring the offering! Should I receive that from your hand?" says the Lord.
14 "But cursed be the swindler who has a male in his flock and vows it, but sacrifices a blemished animal to the Lord, for I am a great King," says the Lord of hosts, "and My name is feared among the nations."
Malachi 2
1 "And now this commandment is for you, O priests.
2 If you do not listen, and if you do not take it to heart to give honor to My name," says the Lord of hosts, "then I will send the curse upon you and I will curse your blessings; and indeed, I have cursed them already, because you are not taking it to heart.
3 Behold, I am going to rebuke your offspring, and I will spread refuse on your faces, the refuse of your feasts; and you will be taken away with it.
4 Then you will know that I have sent this commandment to you, that My covenant may continue with Levi," says the Lord of hosts.
5 "My covenant with him was one of life and peace, and I gave them to him as an object of reverence; so he revered Me and stood in awe of My name.
6 True instruction was in his mouth and unrighteousness was not found on his lips; he walked with Me in peace and uprightness, and he turned many back from iniquity.
7 For the lips of a priest should preserve knowledge, and men should seek instruction from his mouth; for he is the messenger of the Lord of hosts.
8 But as for you, you have turned aside from the way; you have caused many to stumble by the instruction; you have corrupted the covenant of Levi," says the Lord of hosts.
