I could have sworn there was a verse, similar to Jesus speaking with the Pharisees about cleansing the inside of the cup, but it was something like this:
you should have [attended to the internal] first without failing to [attend to the external]
Only, I cannot find such a verse. I suspect that it really is the talk about the cup or dish with the Pharisees and I’ve just remembered it incorrectly.
Thanks for confirmation either way.
