The devil was a murderer from the beginning.

John 8:44-47 [44] Ye are of your father the devil, and the lusts of your father you will do. He was a murderer from the beginning, and abode not in the truth, because there is no truth in him. When he speaks a lie, he speaks of his own, for he is a liar and the father of it. [45] And because I tell you the truth, ye believe me not. [46] Which of you convinces me of sin? And if I say the truth, why do you not believe me?   [47] He that is of God heareth God's words: ye therefore hear them not, because ye are not of God.   According to the Bible, Cain was the first human born and the first murderer, killing his brother Abel as described in Genesis 4:1–16.   Cain is the progenitor for what I am simply calling the abject lineage of the Bible. They are the firstborn sons of the great early patriarchs of Genesis, consisting of Cain, Ishmael, and Esau. The abject sons carry with them the blood of the elect,   the Talmud, the descendants of Esau are the Romans (and, to a greater extent, all Europeans) 1 Maccabees 1:2-9 [2]And made many wars, and won many strong holds, and slew the kings of the earth, [3]And went through to the ends of the earth, and took spoils of many nations, insomuch that the earth was quiet before him; whereupon he was exalted and his heart was lifted up. [4]And he gathered a mighty strong host and ruled over countries, and nations, and kings, who became tributaries unto him. [5]And after these things he fell sick, and perceived that he should die. [6]Wherefore he called his servants, such as were honourable, and had been brought up with him from his youth, and parted his kingdom among them, while he was yet alive. [7]So Alexander reigned twelves years, and then died. [8]And his servants bare rule every one in his place. [9]And after his death they all put crowns upon themselves; so did their sons after them many years: and evils were multiplied in the earth.
