Whoever humbles himself will be exalted

Matthew 23:1-12
You have only one Master and you are all brothers. Do not to be called 'Rabbi'
You have one Father, and he is in heaven. Do not call anyone on earth 'father'
You have one Teacher, the Christ. Do not be called 'teacher'
The greatest among you will be your servant. For whoever exalts himself will be humbled, and whoever humbles himself will be exalted.
You must obey them, the teachers of the law and the Pharisees,  and do everything the tell you, but do not do what they do.
Moses' seat/chair: Meaning they are the authorized interpreters of the law God gave through Moses.
Teacher word is used today of a 'professor'
Why?
Obey the commandments of the Lord but do not follow what the Pharisees do, for they do not response what they preaching. There are different between doing and knowing.
Humble myself is the basic altitude of Christian. For I am nothing without Jesus.
Even I be called teacher in my office, do not forget to serve my staff. I am not really teacher but a coworker.
Jesus launches into a scathing attack on Israels legalistic, but much-respected religious leaders.
How?
Be humble and serve others for Jesus is the Lord, my master is the Lord.
