Genesis 12:3 - And I will bless them that bless thee, and curse him that curseth thee: and in thee shall all families of the earth be blessed.
>Whoever curses Jews is cursed

Deut 23:3-4 - An Ammonite or Moabite shall not enter into the congregation of the LORD; even to their tenth generation shall they not enter into the congregation of the LORD for ever:
Because they met you not with bread and with water in the way, when ye came forth out of Egypt; and because they hired against thee Balaam the son of Beor of Pethor of Mesopotamia, to curse thee.
>The blessing applies spiritually to all physical Jews, anyone of the seed of Jacob. How do I know? Because anyone who cursed or afflicted the children of Israel was cursed, like the Moabites

Ex. 17:16 - For he said, Because the LORD hath sworn that the LORD will have war with Amalek from generation to generation.
>Another example of Gen 12:3 applying to all physical Jews is when the Amalek afflicted the Jews they were cursed
