What is [way] The End Of The Way?
This phrase comes from Hebrew, and its meaning is something extraordinarily good. If we need to go through a way in order to get somewhere, the end of this way would be the place we want to get to or a condition we desire to be in -- and this place or condition is of course valuable for us.
Hence, "the end of the way" is something REALLY good.
"I am telling you, this movie is the end of the way".
"what a cake, the end of the way".
