Clement of Rome

Every kind of honour and happiness was bestowed upon you, and then was fulfilled that which is written, "My beloved ate and drank, and was enlarged and became fat, and kicked." [Deuteronomy 32:15] Hence flowed emulation and envy, strife and sedition, persecution and disorder, war and captivity. So the worthless rose up against the honoured, those of no reputation against such as were renowned, the foolish against the wise, the young against those advanced in years. For this reason righteousness and peace are now far departed from you, inasmuch as every one abandons the fear of God, and has become blind in His faith, neither walks in the ordinances of His appointment, nor acts a part becoming a Christian, but walks after his own wicked lusts, resuming the practice of an unrighteous and ungodly envy, by which death itself entered into the world. [Wisdom 2:24]

For thus it is written: "And it came to pass after certain days, that Cain brought of the fruits of the earth a sacrifice unto God; and Abel also brought of the firstlings of his sheep, and of the fat thereof. And God had respect to Abel and to his offerings, but Cain and his sacrifices He did not regard. And Cain was deeply grieved, and his countenance fell. And God said to Cain, Why are you grieved, and why is your countenance fallen? If you offer rightly, but do not divide rightly, have you not sinned? Be at peace: your offering returns to yourself, and you shall again possess it. And Cain said to Abel his brother, Let us go into the field. And it came to pass, while they were in the field, that Cain rose up against Abel his brother, and slew him." [Genesis 4:3-8] You see, brethren, how envy and jealousy led to the murder of a brother. Through envy, also, our father Jacob fled from the face of Esau his brother [Genesis 27:41-45]. Envy made Joseph be persecuted unto death, and to come into bondage. [Genesis 37:18-28] Envy compelled Moses to flee from the face of Pharaoh king of Egypt, when he heard these words from his fellow-countryman, "Who made you a judge or a ruler over us? Will you kill me, as you killed the Egyptian yesterday?" [Exodus 2:14] On account of envy, Aaron and Miriam had to make their abode without the camp. [Numbers 12:14-15] Envy brought down Dathan and Abiram alive to Hades, through the sedition which they excited against God's servant Moses. [Numbers 16:33] Through envy, David not only underwent the hatred of foreigners, but was also persecuted by Saul king of Israel. [1 Samuel 21:10-15]
