And Adam knew Eve as his wife, and she became pregnant and bore Cain; and she said, I have gotten and gained a man with the help of the Lord. And [next] she gave birth to his brother Abel. Now Abel was a keeper of sheep, but Cain was a tiller of the ground. And in the course of time Cain brought to the Lord an offering of the fruit of the ground. read more.
And Abel brought of the firstborn of his flock and of the fat portions. And the Lord had respect and regard for Abel and for his offering, But for Cain and his offering He had no respect or regard. So Cain was exceedingly angry and indignant, and he looked sad and depressed. And the Lord said to Cain, Why are you angry? And why do you look sad and depressed and dejected? If you do well, will you not be accepted? And if you do not do well, sin crouches at your door; its desire is for you, but you must master it.

A son honors his father, and a servant his master. If then I am a Father, where is My honor? And if I am a Master, where is the [reverent] fear due Me? says the Lord of hosts to you, O priests, who despise My name. You say, How and in what way have we despised Your name? By offering polluted food upon My altar. And you ask, How have we polluted it and profaned You? By thinking that the table of the Lord is contemptible and may be despised. When you [priests] offer blind [animals] for sacrifice, is it not evil? And when you offer the lame and the sick, is it not evil? Present such a thing [a blind or lame or sick animal] now to your governor [in payment of your taxes, and see what will happen]. Will he be pleased with you? Or will he receive you graciously? says the Lord of hosts. read more.
Now then, I [Malachi] beg [you priests], entreat God [earnestly] that He will be gracious to us. With such a gift from your hand [as a defective animal for sacrifice], will He accept it or show favor to any of you? says the Lord of hosts. Oh, that there were even one among you [whose duty it is to minister to Me] who would shut the doors, that you might not kindle fire on My altar to no purpose [an empty, futile, fruitless pretense]! I have no pleasure in you, says the Lord of hosts, nor will I accept an offering from your hand.
