That's it!
The chapter is talking about the gentiles.Ray Franz in COC points this out and tells how at least one member of the GB said that it was "obvious Jesus was talking about the gentiles".
When I first read COC 16 years ago it was the main thing that blew me away!
Moreove....r Ray also went on to demolish the literal 144,000 figure as everything in Rev 7th chapter is symbolic and the WT takes it so except one thing the 144,000 figure they take out of context as literal.
