When Yeshua was cleansing the temple from things that should not be there, did you notice how he cleansed it of 'blind and lame'? 2Sa 5:6-8, according to Mat 21:14? I notice this today.

As an important detail not present in the other Gospels, I suppose it supports Matthean Posteriority. A writer supposedly writing from Matthew is not likely to decide, "Nah, let's leave out those amazing healings. They are not so important."
