I would like to add something beautiful I realised a short while ago.
Simeon and Levi, were cursed.(it will turn beautiful later on, just be patient)
Their sister, Dinah, was raped by Sichem, the son of Hemor, the lord of that land(genesis 34). Hemor wanted to make amends, and let his son marry her.(that's how things were done then).
The sons of Jacob agreed, on the condition that all the men of his city would be circumcised. Hemor agreed to that. when they were all circumcised and weak from the bloodloss, Simeon and Levi came in and murdered all the men in that city.
Jacob cursed them for that, and later on his deathbed when he blesses all his sons(genesis 49). Simeon and Levi are cursed by Jacob, they will be scattered among the other tribes.
Now we go a few centuries later, and at Sinai all tribes, but the tribe of Levi, bow for the golden calf. For this they get the blessing that they will be the priests of Israel.
How are these related? The curse came true. They never got their own plot of land, but where scattered in priest cities, throughout all of Israel.
I think this is a beautiful story which shows that even a curse can turn into a blessing, you won't be punished for the deeds of someone long ago, your destiny in this sense is your own.
About Simeon: his tribe was merged with the tribe of Judah, I don't really know why exactly.
