Deuteronomy 19:9

9 But he'll do it only if you are careful to obey all of the laws I'm commanding you today. I'm commanding you to love the LORD your God. I want you to live always as he wants you to live. When he gives you additional land, you must set apart three more cities.

Deuteronomy 19:9 In-Context

7 That's why I command you to set apart for yourselves three cities.
8 The LORD your God will increase the size of your territory. He took an oath and promised your fathers he would do it. He will give you the whole land he promised them.
9 But he'll do it only if you are careful to obey all of the laws I'm commanding you today. I'm commanding you to love the LORD your God. I want you to live always as he wants you to live. When he gives you additional land, you must set apart three more cities.
10 Do it so the blood of those who aren't guilty of murder won't be spilled in your land. It's the land the LORD your God is giving you as your own.
11 But suppose a man hates his neighbor. So he hides and waits for him. Then he attacks him and kills him. And he runs to one of those cities for safety.
