For from days of old no one has heard, nor has ear perceived,
Nor has the eye [a]seen a God besides You,
Who works and acts in behalf of the one who [gladly] waits for Him.
- Isaiah 64:4 Or seen, O God, besides You, what He will do.... The ancient rabbis favored this translation or a variation of it, and some suggested that the unexpressed object (what) is wine preserved since the creation, or Eden. They all applied this verse to the future that follows the millennial kingdom, and was mostly a mystery to them. Heaven, or specifically the New Jerusalem, that follows the kingdom was partially revealed to John in Revelation. There is a story in the Talmud that when King Ahasuerus held a great banquet in Susa for seven days (Esth 1:5), he arrogantly asked the Jews if God could do better for them than that. They quoted this line to him in reply, and said that in the time to come if God provided nothing better for them than this feast, they could tell Him that they had already enjoyed such a feast at the table of Ahasuerus.
King James Version
4 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.Read full chapter
1 Corinthians 2:9
9 but just as it is written [in Scripture],
“Things which the eye has not seen and the ear has not heard,
And which have not entered the heart of man,
All that God has prepared for those who love Him [who hold Him in affectionate reverence, who obey Him, and who gratefully recognize the benefits that He has bestowed].”(A)
