You seem to rip verses out of context to support your eisegesis.
shalom b'SHEM Yah'shua HaMashiach Jer 31:34 "They will not teach again,
Shabbat Shalom
each man his neighbor and each man his brother,
saying, 'Know YHvH,
' for they will all know Me,
from the least of them to the greatest of them,"
declares YHvH,
"for I will forgive their iniquity,
and their sin I will remember no more."
what you posted still does not change the fact that YHVH did not make a covenant with pagan gentiles as pagan gentiles have always been welcome to leave their false religion & religious practices behind in order join the House of YHVH & be one of the brethren.
Too bad modern Christianity worshiped body count over Scripture when they adopted & to this day, still keep those pagan practices that YHVH calls abomionations.
