Gen 49:5-7 was indeed a prophecy concerning Simeon and Levi. They
They were scattered/dispersed due to their anger and when you go into Exodus we see someone who represented this prophecy as Moses who was from Levi tribe. Moses was first taken away from Israel during his birth after Pharaoh ordered the killing of male child that was born. He then went to live in Egypt after being adopted by Pharaoh’s daughter.
The prophecy written in Gen 49:5-7 is then fulfilled when Moses killed the Egyptian who was beating a hebrew slave. Moses later ran away from Pharaoh and fleefled to Midian after Pharaoh heard the news of the Egyptian that he killed, this. This is written in ExExodus 2:11-23. So here Here we see that Levi tribe was chosen and the representative was Moses who became the promised pastor at that time and led Israelites out of Egypt (Hell) to Canaan (Heaven).
