Where in Old Testament is said something like we must be cautious reading it because prophets can make mistakes?

A week ago I was reading Matthew, and at Mt 2:15 and 2:17 he write about Old Testament prophecies. Searching for it, maybe in Jeremiah, I read something like *'**we must be cautious reading the Holy Scriptures because prophets can make mistakes**'*. I found it a beautiful message, but at the time, when I was searching for the prophecy referenced by Matthew, I don't pay too much attention to it, and today I'm not able to find it again. Can someone point me the location of some versicle that could be that?
