Joshua 1:16

12 And to the Reubenites and the Gadites and the half-tribe of Manasseh, Joshua said,

13 Keep in mind what Moses, the servant of the Lord, said to you, The Lord your God is sending you rest and will give you this land.

14 Your wives, your little ones, and your cattle will be kept here in the land which Moses gave you on this side of Jordan; but you, the fighting-men, are to go over before your brothers, armed, to give them help;

15 Till the Lord has given your brothers rest, as he has given it to you, and they have taken their heritage in the land which the Lord your God is giving them: then you will go back to the land of your heritage which Moses, the servant of the Lord, gave you on the east side of Jordan.

16 Then they said to Joshua in answer, Whatever you say to us we will do, and wherever you send us we will go.

17 As we gave attention to Moses in all things, so we will give attention to you: and may the Lord your God be with you as he was with Moses.

18 Whoever goes against your orders, and does not give attention to all your words, will be put to death: only take heart and be strong.
