Exodus 20:13
13“You shall not murder.
Genesis 4:1–15
4:1Now Adam knew Eve his wife, and she conceived and bore Cain, saying, “I have gotten a man with the help of the LORD.” 2And again, she bore his brother Abel. Now Abel was a keeper of sheep, and Cain a worker of the ground. 3In the course of time Cain brought to the LORD an offering of the fruit of the ground, 4and Abel also brought of the firstborn of his flock and of their fat portions. And the LORD had regard for Abel and his offering, 5but for Cain and his offering he had no regard. So Cain was very angry, and his face fell. 6The LORD said to Cain, “Why are you angry, and why has your face fallen? 7If you do well, will you not be accepted? And if you do not do well, sin is crouching at the door. Its desire is for you, and you must rule over it.”
8Cain spoke to Abel his brother. And when they were in the field, Cain rose up against his brother Abel and killed him. 9Then the LORD said to Cain, “Where is Abel your brother?” He said, “I do not know; am I my brother’s keeper?” 10And the LORD said, “What have you done? The voice of your brother’s blood is crying to me from the ground. 11And now you are cursed from the ground, which has opened its mouth to receive your brother’s blood from your hand. 12When you work the ground, it shall no longer yield to you its strength. You shall be a fugitive and a wanderer on the earth.” 13Cain said to the LORD, “My punishment is greater than I can bear. 14Behold, you have driven me today away from the ground, and from your face I shall be hidden. I shall be a fugitive and a wanderer on the earth, and whoever finds me will kill me.” 15Then the LORD said to him, “Not so! If anyone kills Cain, vengeance shall be taken on him sevenfold.” And the LORD put a mark on Cain, lest any who found him should attack him.
Matthew 5:21–22
21“You have heard that it was said to those of old, ‘You shall not murder; and whoever murders will be liable to judgment.’ 22But I say to you that everyone who is angry with his brother will be liable to judgment; whoever insults his brother will be liable to the council; and whoever says, ‘You fool!’ will be liable to the hell of fire.
