wt 98 2/1 p.19, par. 6 - "Further, other sheep lay hold of the new covenant just as foreigners of old laid hold of the Law covenant. In what way? Not by becoming participants in it but by submitting to the laws associated with it and benefiting from its arrangements."
Exodus 12:48, 49, Deuteronomy 29:10-15, and Ezekiel 47:21-23 show beyond the shadow of a doubt that this dogma of the WTBTS/JW's blasphemes the Holy Scriptures in order to create the false type/antitype of the foreigners & the other sheep.
This lie then perpetuates their Black Memorial, where every O.S. JW rejects the New Covenant.
Rahab and Ruth were foreigners and were accepted as full members of the nation of Israel and participants of the Mosaic Covenant.
If they hadn't been, the Messianic lineage would have been corrupted by non-Israelites. They and their descendants all received inheritances in the nation of Israel.
p.s. Of course the biggest lie the org has ever told is that God & Jesus personally chose the WTBTS in 1919 as their "earthly organization." 🤣🤣🤣🤣🤣🤣 Try proving that with Scriptures, JW's!
