Genesis 4:3-5, 15, 25

When it was time for the harvest, Cain presented some of his crops as a gift to the LORD. Abel also brought a gift—the best portions of the firstborn lambs from his flock. The LORD accepted Abel and his gift, but he did not accept Cain and his gift. This made Cain very angry, and he looked dejected.

The LORD replied, “No, for I will give a sevenfold punishment to anyone who kills you.” Then the LORD put a mark on Cain to warn anyone who might try to kill him.

Adam had sexual relations with his wife again, and she gave birth to another son. She named him Seth, for she said, “God has granted me another son in place of Abel, whom Cain killed.”
