Verily, verily, I say unto

 The book of John in the Bible has the phrase, "Verily, verily, I say unto" twenty five times. "Verily, verily " means "this is important, pay close attention!". So, why do Matthew, Mark and Luke omit this phrase? Are they skipping "the good stuff?"

Are these twenty five unique statements that God in a flesh body made in John only? Or are the basic statements in the other books without "verily, verily"?
