Samurai

The samurai serves his daimyo, or Master, with absolute loyalty, even to the death. In fact, the word samurai means, "those who serve"...

"Let each of you look not only to his own interests, but also to the interests of others. Have this mind among yourselves, which is yours in Christ Jesus, who, though he was in the form of God, did not count equality with God a thing to be grasped, but emptied himself, by taking the form of a servant, being born in the likeness of men. And being found in human form, he humbled himself by becoming obedient to the point of death, even death on a cross." - Philippians 2:4-8 ESV

"The greatest among you shall be your servant." - Matthew 23:11 ESV
