Jesus told those who sought to kill Him that they were doing the lusts or fulfilling the desires of their father, the devil, who was a MURDERER from the beginning:
"Ye are of your father the devil, and the lusts of your father ye will do. He was a murderer from the beginning, and abode not in the truth, because there is no truth in him. When he speaketh a lie, he speaketh of his own: for he is a liar, and the father of it." (John 8:44)
The Greek word "anthrōpoktonos" which is translated as "murderer" only appears in two other places in the entire New Testament in the following verse:
"Whosoever hateth his brother is a murderer: and ye know that no murderer hath eternal life abiding in him." (I John 3:15)
Jesus was crucified by MURDERERS...and they are the very first ones whom He sent His disciples to preach to after His resurrection from the dead. Stephen prayed that God would not let the sin of his MURDERERS be laid to their charge as they were stoning him to death. Would you or anybody else like to show me where Jesus' disciples went out and avenged the blood of Stephen in alleged fulfillment of the Genesis verse that's being wildly thrown about on this thread? For crying out loud, Paul watched the clothes of them who stoned Stephen and he later became possibly the greatest apostle of all time. Perhaps Peter, James, John or somebody else should have offed his head first? Some people here don't know what manner of spirit they're of:
"And it came to pass, when the time was come that he should be received up, he stedfastly set his face to go to Jerusalem, And sent messengers before his face: and they went, and entered into a village of the Samaritans, to make ready for him. And they did not receive him, because his face was as though he would go to Jerusalem. And when his disciples James and John saw this, they said, Lord, wilt thou that we command fire to come down from heaven, and consume them, even as Elias did? But he turned, and rebuked them, and said, Ye know not what manner of spirit ye are of. For the Son of man is not come to destroy men's lives, but to save them. And they went to another village." (Luke 9:51-56)
