1 Samuel 18:29

⁴Then I saw all the labor and achievement that is the envy of a man’s neighbor. This also is vanity and a striving after wind.

⁴Abel also brought some of the firstborn of his flock and of its fat. The LORD respected Abel and his offering, ⁵but he didn’t respect Cain and his offering. Cain was very angry, and the expression on his face fell. ⁶The LORD said to Cain, “Why are you angry? Why has the expression of your face fallen? ⁷If you do well, won’t it be lifted up? If you don’t do well, sin crouches at the door. Its desire is for you, but you are to rule over it.” ⁸Cain said to Abel, his brother, “Let’s go into the field.” While they were in the field, Cain rose up against Abel, his brother, and killed him.

⁵³So from that day forward they took counsel that they might put him to death.

¹⁹You believe that God is one. You do well. The demons also believe—and shudder.

¹²Saul was afraid of David, because the LORD was with him, and had departed from Saul.

¹²unlike Cain, who was of the evil one and killed his brother. Why did he kill him? Because his deeds were evil, and his brother’s righteous.

¹³Don’t be surprised, my brothers, if the world hates you. ¹⁴We know that we have passed out of death into life, because we love the brothers. He who doesn’t love his brother remains in death. ¹⁵Whoever hates his brother is a murderer, and you know that no murderer has eternal life remaining in him.

¹²The wicked plots against the just, and gnashes at him with his teeth. ¹³The Lord will laugh at him, for he sees that his day is coming. ¹⁴The wicked have drawn out the sword, and have bent their bow, to cast down the poor and needy, to kill those who are upright on the path.

¹⁵When Saul saw that he behaved himself very wisely, he stood in awe of him.
