I’m sure this is stretching it a bit and I have lived a sheltered life, however paragraph 8 of today’s WT Study of Marriage of the Lamb- says the King's (Jehovah) daughter is the 144,000 as adopted “children” of Jehovah. They are to marry Gods son Jesus the bridegroom.
Yes I know they are not “blood relatives”, but how often do you hear of adopted kids marrying within their adopted family of brothers or sisters?
