Genesis 4:1-8 - The First Family - ERV
1 Adam had sexual relations with his wife Eve. She became pregnant and gave birth to a son. She named him Cain.[a] Eve said, “With the Lord’s help, I have made a man!”
2 Eve gave birth again to Cain’s brother Abel. Abel became a shepherd, and Cain became a farmer.
The First Murder
3-4 At harvest time,[b] Cain brought a gift to the Lord. He brought some of the food that he grew from the ground, but Abel brought some animals from his flock. He chose some of his best sheep and brought the best parts from them.[c]
The Lord accepted Abel and his gift.
5 But he did not accept Cain and his offering. Cain was sad because of this, and he became very angry.
6 The Lord asked Cain, “Why are you angry? Why does your face look sad?
7 You know that if you do what is right, I will accept you. But if you don’t, sin is ready to attack you. That sin will want to control you, but you must control it.”[d]
8 Cain said to his brother Abel, “Let’s go out to the field.”[e] So they went to the field. Then Cain attacked his brother Abel and killed him.

Ephesians 4:26-27 - ERV
26 “When you are angry, don’t let that anger make you sin,”[a] and don’t stay angry all day.
27 Don’t give the devil a way to defeat you.
