And yet, how many other verses are read in light of no other verse in the Bible. The "1,000 Years" is a good example. Mentioned only one time in the entire Bible, yet a doctrine has been built around it.
If you are talking about Rev 20 where the "thousand years" is mentioned in verses 2, 3, 4, 5, 6 and 7, then with respect to the time of the imprisonment of Satan in the Bottomless pit for 1,000 years, then the meaning of Greek Root, "chilioi," on which the above use of "chilioi" is found in in the following 3 Greek words: -
Strong's Greek 5507
11 Occurrences
χίλια chilia — 8 Occ. - 2 Peter 3:8, 3:8, Revelation 20: 2, 20: 3, 20: 4, 20: 5, 20: 6, 20: 7
χιλίας cholias — 2 Occ. - Revelation 11: 3, 12: 6
χιλίων chiliōn — 1 Occ. - Revelation 14: 20
is not as definitive as the English translations suggest.
Strong's definition of this Greek Root Word is that its meaning is of uncertain affinity, but that it is given the meaning of 1,000,.
Now this time period of imprisonment in the Bottomless Pit is mentioned in the OT but the duration of the length of this imprisonment is expressed as "many days" in Isaiah 24: 22 and as such it does not provide a prescriptive time period as found in the translation of the above verses from the NT.
Be that as it may be, I also agree that a doctrine has been created around this time period which is not supported by the scriptures but has been cobbled together using scripture to create a justified doctrine around those peoples desire for something that is not scriptural. In a sense, they are changing God's intent and purpose for the ages of the Age.
From my ponderings on the meaning of "chilioi," I have not yet nailed it down to the Roman understanding of the numerical value of "chilioi" as some others have done of M or 1,000 and I am still considering as to whether or not there is another value that should be considered with respect to God's numerical system. The jury is still out for me and I may not be able to come to a firm conclusion while I am still drawing breath. Whether it has a value of 1,000 or a value close to 1,000 does not change the fact that a long finite period of time was being indicated in Revelation 20.
