Martin Luther, Matthew – and the Devil

Last night I was working away on the sermon book and I wanted to use Luther’s remark that even Matthew in writing the gospel named for him was influenced by Satan. But, then I could not for the life of me recall where I read that. I tried checking around in my books, did a google search, but I cannot seem to find it. So, I need some help. Anyone know a source for this? Or am I completely wrong and it was someone else who said this. But it does sound like something Luther might have said. I can almost picture the Latin version of the phrase but I can’t remember where it came from. Help!
