1 Peter 5:1-5

1. To the elders among you, I appeal as a fellow elder, a witness of Christ's sufferings and one who also will share in the glory to be revealed:
2. Be shepherds of God's flock that is under your care, serving as overseers--not because you must, but because you are willing, as God wants you to be; not greedy for money, but eager to serve;
3. not lording it over those entrusted to you, but being examples to the flock.
4. And when the Chief Shepherd appears, you will receive the crown of glory that will never fade away.
5. Young men, in the same way be submissive to those who are older. All of you, clothe yourselves with humility toward one another, because, "God opposes the proud but gives grace to the humble."

Galatians 5:13-15

13. You, my brothers, were called to be free. But do not use your freedom to indulge the sinful nature ; rather, serve one another in love.
14. The entire law is summed up in a single command: "Love your neighbor as yourself."
15. If you keep on biting and devouring each other, watch out or you will be destroyed by each other.

Matthew 20:20-28

20. Then the mother of Zebedee's sons came to Jesus with her sons and, kneeling down, asked a favor of him.
21. "What is it you want?" he asked. She said, "Grant that one of these two sons of mine may sit at your right and the other at your left in your kingdom."
22. "You don't know what you are asking," Jesus said to them. "Can you drink the cup I am going to drink?" "We can," they answered.
23. Jesus said to them, "You will indeed drink from my cup, but to sit at my right or left is not for me to grant. These places belong to those for whom they have been prepared by my Father."
24. When the ten heard about this, they were indignant with the two brothers.
25. Jesus called them together and said, "You know that the rulers of the Gentiles lord it over them, and their high officials exercise authority over them.
26. Not so with you. Instead, whoever wants to become great among you must be your servant,
27. and whoever wants to be first must be your slave--
28. just as the Son of Man did not come to be served, but to serve, and to give his life as a ransom for many."
