Simeon and Levi were violent and lawless. Instead of seeking justice, they allowed their uncontrolled anger to control them and ignored the value of life (34:24–29).
I will disperse them: Simeon's land mostly became part of Judah's (Joshua 19:1, 9). Levi was given a more honorable future because the Levites became the priestly tribe (see Exodus 32:25–29). But they did not have their own region (Joshua 21).
