Luke 22:24-27
New King James Version
The Disciples Argue About Greatness
24 Now there was also a dispute among them, as to which of them should be considered the greatest. 25 And He said to them, “The kings of the Gentiles exercise lordship over them, and those who exercise authority over them are called ‘benefactors.’ 26 But not so among you; on the contrary, he who is greatest among you, let him be as the younger, and he who governs as he who serves. 27 For who is greater, he who sits at the table, or he who serves? Is it not he who sits at the table? Yet I am among you as the One who serves.

1 Timothy 3:8-13
New King James Version
Qualifications of Deacons
8 Likewise deacons must be reverent, not double-tongued, not given to much wine, not greedy for money, 9 holding the [a]mystery of the faith with a pure conscience. 10 But let these also first be tested; then let them serve as deacons, being found blameless. 11 Likewise, their wives must be reverent, not [b]slanderers, temperate, faithful in all things. 12 Let deacons be the husbands of one wife, ruling their children and their own houses well. 13 For those who have served well as deacons obtain for themselves a good standing and great boldness in the faith which is in Christ Jesus.
