While on the campaign trail in Iowa, Cruz began referencing the biblical verse 2 Chronicles 7:14 ("Second Chronicles") before he was interrupted by someone in the crowd at the town hall who joked he meant "Two Chronicles."
"Well, you know, two Corinthians walk into a bar..." the Texas senator quipped.
Cruz was making light of Trump's gaffe during a speech at Liberty University last week where he referenced "2 Corinthians" instead of "Second Corinthians," as it's commonly known.
Trump later blamed evangelical activist Tony Perkins for the gaffe, saying "he actually wrote out the 2" for his speech and adding that people in other places of the world "say 2."
Cruz and Trump are running neck and neck in Iowa polls and are battling for support among evangelical voters in the Hawkeye State a week out from the caucuses there Feb. 1.
