All of them had the Greek texts sosandso - the translators hid the truth behind their futurist theology.
But that said, even in the KJV imminence is stamped all over the pages of the NT.
That is frequently true.
Only preconceptions and false expectations makes "at hand" and "shortly come to pass" events hundreds of years into the future.
Here, these OT prophets (700-800 BC) are speaking about the "day of the Lord", referring to the end times, and it still has not happened. Even if you insist the "day of the Lord" happened in 66-70 AD, that is still 700-800 years AFTER those prophecies were spoken.
Isaiah 13:
6) Wail, for
the day of the Lord is near; it will come like destruction from the Almighty.
Isaiah 29:
17)
Is it not yet a very little while, and Lebanon shall be turned into a fruitful field, and the fruitful field shall be esteemed as a forest?
Isaiah 51: (NIV)
5)
My righteousness draws near speedily, my salvation is on the way, and my arm will bring justice to the nations. The islands will look to me and wait in hope for my arm.
Zeph 1:
14)
The great day of the LORD is near, it is near, and hasteth greatly, even the voice of the day of the LORD: the mighty man shall cry there bitterly.
Joel 1:
15) Alas for that day!
For the day of the Lord is near; it will come like destruction from the Almighty.
Joel 2:
1) Blow the trumpet in Zion; sound the alarm on my holy hill. Let all who live in the land tremble, for
the day of the Lord is coming. It is close at hand—
Joel 3:
14) Multitudes, multitudes in the valley of decision! For
the day of the Lord is near in the valley of decision.
There are others (Obadiah and Haggai).
God's use of "near", "hastily", "coming soon", etc, is just the way He chose to speak at times, in both the OT and NT.
