Ok the baby that was born was Agag...and I remembered wrong, we don't know who (as a people) descended from the Amalekites, but that act of disobedience is seen as the reason that so many take exception and seek the annihilation of Jews...
"
Today, we have no way of identifying the descendants of Amalek—his descendents a mixed in amongst the nations, but we do know that the Amalekite ideology lives on. There has been more than one occasion when people have arisen bent on exterminating the Jews. The Bible itself mentions that the battle with Amalek represents the ultimate struggle in history between good evil with total victory achieved only at the End of Days.
...I [God] shall surely erase the memory of Amalek from under the heavens…God maintains a war against Amalek from generation to generation.” (Exodus 17:14-16)
One such example was Haman, the Persian minister who tried to annihilate the Jews in the time of Queen Esther (355 BCE). And Hitler certainly espoused Amalekite ideology:
Yes, we are barbarians! We want to be barbarians. It is an honorable title to us ... Providence has ordained that I should be the greatest liberator of humanity. I free man from ... the degrading self-mortification of a false vision called conscience and morality ... Conscience is a Jewish invention. (
Hitler Speaks, pp. 87, 220-222.)"
