4 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.

Read Isaiah 64:4 Using Other Translations

For since the beginning of the world men have not heard, nor perceived by the ear, neither hath the eye seen, O God, beside thee, what he hath prepared for him that waiteth for him.
From of old no one has heard or perceived by the ear, no eye has seen a God besides you, who acts for those who wait for him.
For since the world began, no ear has heard and no eye has seen a God like you, who works for those who wait for him!
