In his First Epistle to the Corinthians, Paul says that
“However, as it is written: ‘No eye has seen, no ear has heard, no mind has conceived what God has prepared for those who love him.'” (1 Corinthians 2:9)
It is claimed that Paul had paraphrase the above citation from Isaiah:
“Since ancient times no one has heard, no ear has perceived, no eye has seen any God besides you, who acts on behalf of those who wait for him.” (Isaiah 64:4)
This is actually inaccurate, as Paul had actually quoted the above from the ‘apocryphal books of Elijah’ and not Isaiah 64:4. Apostolic Christians such as Origen and Jerome had confirmed the following about the source of Paul’s quote.
