Genesis 49:27-28

27 Benjamin is like a hungry wolf. He kills an animal and he eats it in the morning. In the evening, he gives what remains to his people.’

49:27Jacob is saying that Benjamin's descendants will attack their enemies and kill them in the morning. In the evening, they will share the things that they have taken from their enemies.

28 All these are ancestors of the 12 tribes of Israel. This is what their father said to them when he blessed them. He spoke to each of his sons the words that were right for them and for their descendants.

49:28The descendants of each of Jacob's sons would become the tribes of Israel.
