7:4 And I heard the number of those who were sealed, one hundred and forty-four thousand sealed from every tribe of the sons of Israel:
And I heard the number of those who were sealed, 144,000 sealed from every tribe of the SONS of ISRAEL:
There are three views of this verse:
It is most likely that the second view should be held. The Revelation of Jesus Christ is a very precise book as far as numbers are concerned. The seven churches, the seven seals, the seven spirits, and so on indicates that this exact sealing is precisely 144,000 from the SONS of ISRAEL. Likewise, the Revelation is not a Gentile verses Jews book but rather a Loyalty to God vs. Loyalty to the beast book.
