The Old Testament is about the Jews and God. God gives them an alternative, do what I say and the world will be a different place, peace will flourish and love and kindness will become the norm. Ignore my covenants and you will surfer terribly for it which includes but not limited to becoming a proverb and byword wherever you go.
(Deu 11:26 KJV) Behold, I set before you this day a blessing and a curse;
(Due 11:27 KJV) A blessing, if ye obey the commandments of the LORD your God, which I command you this day:
(Deu 11:28 KJV) And a curse, if ye will not obey the commandments of the LORD your God, but turn aside out of the way which I command you this day, to go after other gods, which ye have not known.
(Exo 19:5 KJV) Now therefore, if ye will obey my voice indeed, and keep my covenant, then ye shall be a peculiar treasure unto me above all people: for all the earth is mine:
(Deu 28:58 KJV) If thou wilt not observe to do all the words of this law that are written in this book, that thou mayest fear this glorious and fearful name, THE LORD THY GOD;
(Deu 4:27 KJV) And the LORD shall scatter you among the nations, and ye shall be left few in number among the heathen, whither the LORD shall lead you.
(Deu 28:37 KJV) And thou shalt become an astonishment, a proverb, and a byword, among all nations whither the LORD shall lead thee.
This no one can deny, they were scattered, they were left few in number and those numbers are decreasing by the day. And the byword is well known. If you dont get the actual connection here then that is your problem; not mine. As a gentile I would rather see a peaceful world where we all work together to solve the many problems that lay ahead but if not then we will survive, but you and yours will NOT.
BTW Scripture also says they will be gathered for the final judgment and that day has arrived as well. They be gathered and the place they were gathered is called ISRAEL. The only thing left is the judgment and that day will arrive in your lifetime. So enjoy it while you can.
