Ecclesiastes 4:4Again, I considered all travail, and every right work, that for this a man is envied of his neighbour. This is also vanity and vexation of spirit.
Genesis 4:4-8And Abel, he also brought of the firstlings of his flock and of the fat thereof. And the LORD had respect unto Abel and to his offering: But unto Cain and to his offering he had not respect. And Cain was very wroth, and his countenance fell. And the LORD said unto Cain, Why art thou wroth? and why is thy countenance fallen? If thou doest well, shalt thou not be accepted? and if thou doest not well, sin lieth at the door. And unto thee shall be his desire, and thou shalt rule over him. And Cain talked with Abel his brother: and it came to pass, when they were in the field, that Cain rose up against Abel his brother, and slew him.
1 Samuel 18:12And Saul was afraid of David, because the LORD was with him, and was departed from Saul.
1 Samuel 18:15Wherefore when Saul saw that he behaved himself very wisely, he was afraid of him.
Psalms 37:12-14The wicked plotteth against the just, and gnasheth upon him with his teeth. The LORD shall laugh at him: for he seeth that his day is coming. The wicked have drawn out the sword, and have bent their bow, to cast down the poor and needy, and to slay such as be of upright conversation.
John 11:53Then from that day forth they took counsel together for to put him to death.
James 2:19Thou believest that there is one God; thou doest well: the devils also believe, and tremble.
1 John 3:12-15Not as Cain, who was of that wicked one, and slew his brother. And wherefore slew he him? Because his own works were evil, and his brother's righteous. Marvel not, my brethren, if the world hate you. We know that we have passed from death unto life, because we love the brethren. He that loveth not his brother abideth in death. Whosoever hateth his brother is a murderer: and ye know that no murderer hath eternal life abiding in him.
