Mark 9:30-35

Then they departed from there and passed through Galilee, and He did not want anyone to know it. For He taught His disciples and said to them, “The Son of Man is being betrayed into the hands of men, and they will kill Him. And after He is killed, He will rise the third day.” But they did not understand this saying, and were afraid to ask Him. Then He came to Capernaum. And when He was in the house He asked them, “What was it you disputed among yourselves on the road?” But they kept silent, for on the road they had disputed among themselves who would be the greatest. And He sat down, called the twelve, and said to them, “If anyone desires to be first, he shall be last of all and servant of all.”
