Isaiah 64.4
Septuagint

apo tou aiwnoV ouk hkousamen, oude oi ofqalmoi hmwn eidon qeon plhn sou, kai ta erga sou, a poihseiV toiV upomenousin eleon 

New Testament - 1 Corinthians 2.9

a ofqalmoV ouk eiden kai ouV ouk hkousen kai epi kardian anqrwpou ouk anebh, a htoimasen o qeoV toiV agapwsin auton
 

Septuagint

From of old we have not heard, neither have our eyes seen a God beside thee, and thy works which thou wilt perform to them that wait for mercy

New Testament

Things which eye saw not, and ear heard not,
And which entered not into the heart of man,
Whatsoever things God prepared for them that love him

Masoretic Text

For from of old men have not heard, nor perceived by the ear, neither hath the eye seen a God besides thee, who worketh for him that waiteth for him

Comments:  This appears to be a very loose quotation.  Yet Paul introduces it with the formula, “as it is written.” 

Jerome [Letter LVII] uses this as an example of paraphrase in the New Testament.  In doing so, however, he translates the ending from Hebrew with “what thou hast prepared for them that wait for thee.”  

The ending, toiV agapwsin auton, also appears in Sirach 1.10.  Both 1 Corinthians and the passage in Sirach deal with God's gift of wisdom.
