What is Itching ears?

Itching ears is a term used in the Bible to describe individuals who seek out messages and doctrines that condone their own lifestyle, as opposed to adhering to the teachings of the apostles. The term is found only once in the Bible, in 2 Timothy 4.

For the time will come when they will not endure sound doctrine; but after their own lusts shall they heap to themselves teachers, having itching ears; And they shall turn away their ears from the truth, and shall be turned unto fables.
