Joshua 1:15

15 until the Lord your God shall have given your brethren rest, as also to you, and they also shall have inherited the land, which the Lord your God gives them; then ye shall depart each one to his inheritance, which Moses gave you beyond Jordan eastward.

Joshua 1:15 In-Context

13 Remember the word which Moses the servant of the Lord commanded you, saying, the Lord your God has caused you to rest, and has given you this land.
14 Let your wives and your children and your cattle dwell in the land, which he has given you; and ye shall go over well armed before your brethren, every one of you who is strong; and ye shall fight on their side;
15 until the Lord your God shall have given your brethren rest, as also to you, and they also shall have inherited the land, which the Lord your God gives them; then ye shall depart each one to his inheritance, which Moses gave you beyond Jordan eastward.
16 And they answered Joshua and said, We will do all things which thou commandest us, and we will go to every place whither thou shalt send us.
17 Whereinsoever we hearkened to Moses we will hearken to thee; only let the Lord our God be with thee, as he was with Moses.
