Genesis 4:1-15, 25
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 tiller of the ground. 3In the course of time Cain brought to the LORD an offering of the fruit of the ground, 4and Abel brought of the firstlings 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 countenance fell. 6The LORD said to Cain, "Why are you angry, and why has your countenance fallen? 7If you do well, will you not be accepted? And if you do not do well, sin is couching at the door;its desire is for you, but you must master it." 8Cain said to Abel his brother, "Let us go out to the field." 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 till 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, thou hast driven me this day away from the ground;and from thy face I shall be hidden;and I shall be a fugitive and a wanderer on the earth, and whoever finds me will slay me." 15Then the LORD said to him, "Not so! If any one slays Cain, vengeance shall be taken on him sevenfold." And the LORD put a mark on Cain, lest any who came upon him should kill him. 25And Adam knew his wife again, and she bore a son and called his name Seth, for she said, "God has appointed for me another child instead of Abel, for Cain slew him."
Psalms 50:1, 8, 16-17, 20-21
1The Mighty One, God the LORD, speaks and summons the earth from the rising of the sun to its setting. 8I do not reprove you for your sacrifices;your burnt offerings are continually before me. 16But to the wicked God says: "What right have you to recite my statutes, or take my covenant on your lips? 17For you hate discipline, and you cast my words behind you. 20You sit and speak against your brother;you slander your own mother's son. 21These things you have done and I have been silent;you thought that I was one like yourself. But now I rebuke you, and lay the charge before you.
