Comparison: an examination of two or more items to establish similarities and differences. (Webster)
In the course of time Cain brought some of the fruits of the soil as an offering to the Lord. 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, but on Cain and his offering he did not look with favor. So Cain was very angry, and his face was downcast. Then the Lord said to Cain, “Why are you angry? Why is your face downcast? 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.”
Genesis 4:3-7 New International Version (NIV)
Now Cain said to his brother Abel, “Let’s go out to the field.” While they were in the field, Cain attacked his brother Abel and killed him. Then the Lord said to Cain, “Where is your brother Abel?” “I don’t know,” he replied. “Am I my brother’s keeper?”
Genesis 4:8-9 (NIV)
When we look in the mirror, we may see a little of Cain in us.
1 Samuel 16 – King Saul
And David came to Saul, and entered his service. Saul loved him greatly, and he became his armor-bearer. Saul sent to Jesse, saying, “Let David remain in my service, for he has found favor in my sight.”
1 Samuel 16:21-22 New Revised Standard Version (NRSV)
As they danced, they sang: “Saul has slain his thousands, and David his tens of thousands.” Saul was very angry; this refrain displeased him greatly. “They have credited David with tens of thousands,” he thought, “but me with only thousands. What more can he get but the kingdom?” And from that time on Saul kept a close eye on David.
