For any active/waking Witnesses, compare the NWT with your Interlinear, and ask yourself how any honest translator could corrupt a verse so blatantly!
In the New World Translation, at Revelation 5:9,10 it says, "because you were slaughtered and with your blood you bought persons for God out of every tribe and tongue and people and nation, and you made them to be a kingdom and priests to our God, and they are to rule as kings over the earth."
However, in the Kingdom Interlinear of the Greek Scriptures, it is worded thus - "because you were slaughtered and you bought to the God in the blood of you out of every tribe and of tongue and people and of nation, and you made them to the God of us kingdom and priests, and they are reigning upon the earth."
From the original Greek translation, it can be clearly seen that this Scripture has been 'doctored' to promulgate a spurious teaching. Most noticeably is the fact that the '144,000' will not be in heaven - they are on the earth. Secondly, the Scripture does not say that they are kings! It merely says that they are "reigning". Reigning as what? Princes! (Psam 45:16; Isaiah 32:1)
Nowhere in the Bible is there even a hint of Jesus sharing his kingship with anyone - not even with his apostles. To them, and them alone, he promised the position of judges, as well as sitting on 12 'thrones'. (Greek 'thronos' - a throne seat; a chair of state having a footstool; assigned to judges i.e. tribunal or bench; to elders) The judging would be done from 12thrones, not 144,000!
Returning to the 144,000; not only are they not depicted as being on thrones in a privileged position in heaven, they are standing and singing and playing harps 'before' the throne, the heavenly elders and the 4 symbolic living creatures - not the other way around! Therefore, the 144,000 are not the object of deference by anyone in heaven.
