read (one) a lesson
To scold, reprimand, or reprove someone severely for an error or mistake. I was read a lesson by my boss last week for messing up the accounting software. I know Mary messed up, but there was no need to read her a lesson for it.
To issue a reprimand: My parents read me a lecture because I had neglected my chores.
