Azeem Rafiq has apologised and said he is "deeply ashamed" for using anti-Semitic language in messages from 2011.
Former spinner Rafiq has spoken of his experiences of racism and bullying at Yorkshire and appeared at a Digital, Culture, Media and Sport select committee this week.
The 30-year-old said he had "absolutely no excuses" for the messages.
"I am incredibly angry at myself and apologise to the Jewish community," he said in a statement.
Rafiq said he had deleted the messages to not cause further offence.
"I have absolutely no excuses. I am ashamed of this exchange," he said.
"I was 19 at the time and hope and believe I am a different person today."
