Genesis 4:1a, 2b, 5b-7, 8b -9a, 10b, 12b-14-15 - Now Adam knew Eve his wife, and she conceived and bore Cain … and … his brother Abel. … Cain was very angry [when God accepted Abel’s sacrifice but not his own], and his face fell. The Lord said to Cain, “Why are you angry, and why has your face fallen? If you do well, will you not be accepted? And if you do not do well, sin is crouching at the door. Its desire is contrary to you, but you must rule over it.” … Cain rose up against his brother Abel and killed him. Then the Lord said to Cain, … “What have you done? The voice of your brother's blood is crying to Me from the ground. … You shall be a fugitive and a wanderer on the earth.” Cain said to the Lord, “My punishment is greater than I can bear. Behold, You have driven me today away from the ground, and from Your face I shall be hidden. … and whoever finds me will kill me.” Then 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.
