1 John 3:17-18 If anyone has this world’s goods and sees his brother in need but closes his eyes to his need–how can God’s love reside in him? Little children, we must not love with word or speech, but with truth and action.
14. James 2:15-17 Suppose a brother or a sister is without clothes and daily food. If one of you says to them, “Go in peace; keep warm and well fed,” but does nothing about their physical needs, what good is it? In the same way, faith by itself, if it is not accompanied by action, is dead.
2 Samuel 1:26 How I weep for you, my brother Jonathan! Oh, how much I loved you! And your love for me was deep, deeper than the love of women!
Romans 12:10 Be devoted to one another in brotherly love; give preference to one another in honor.
1 Peter 3:8 Finally, all of you must live in harmony, be sympathetic, love as brothers, and be compassionate and humble.
Genesis 4New International Version (NIV)
Cain and Abel
4 Adam[a] made love to his wife Eve, and she became pregnant and gave birth to Cain.[b] She said, “With the help of the Lord I have brought forth[c] a man.” 2 Later she gave birth to his brother Abel.
Now Abel kept flocks, and Cain worked the soil. 3 In the course of time Cain brought some of the fruits of the soil as an offering to the Lord. 4 And Abel also brought an offering—fat portions from some of the firstborn of his flock. The Lord looked with favor on Abel and his offering, 5 but on Cain and his offering he did not look with favor. So Cain was very angry, and his face was downcast.
6 Then the Lord said to Cain, “Why are you angry? Why is your face downcast? 7 If you do what is right, will you not be accepted? But if you do not do what is right, sin is crouching at your door; it desires to have you, but you must rule over it.”
8 Now Cain said to his brother Abel, “Let’s go out to the field.”[d] While they were in the field, Cain attacked his brother Abel and killed him.
9 Then the Lord said to Cain, “Where is your brother Abel?”
“I don’t know,” he replied. “Am I my brother’s keeper?”
10 The Lord said, “What have you done? Listen! Your brother’s blood cries out to me from the ground. 11 Now you are under a curse and driven from the ground, which opened its mouth to receive your brother’s blood from your hand. 12 When you work the ground, it will no longer yield its crops for you. You will be a restless wanderer on the earth.”
