And Moses said unto them, If ye will do this thing, if ye will go armed before the LORD to war,
Deuteronomy 3:18-20
18
And I commanded you at that time, saying, The LORD your God hath given you this land to possess it: ye shall pass over armed before your brethren the children of Israel, all that are meet for the war.
19
But your wives, and your little ones, and your cattle, (for I know that ye have much cattle,) shall abide in your cities which I have given you;
20
Until the LORD have given rest unto your brethren, as well as unto you, and until they also possess the land which the LORD your God hath given them beyond Jordan: and then shall ye return every man unto his possession, which I have given you.
Joshua 1:13-15
13
Remember the word which Moses the servant of the LORD commanded you, saying, The LORD your God hath given you rest, and hath given you this land.
14
Your wives, your little ones, and your cattle, shall remain in the land which Moses gave you on this side Jordan; but ye shall pass before your brethren armed, all the mighty men of valour, and help them;
15
Until the LORD have given your brethren rest, as he hath given you, and they also have possessed the land which the LORD your God giveth them: then ye shall return unto the land of your possession, and enjoy it, which Moses the LORD'S servant gave you on this side Jordan toward the sunrising.
Joshua 4:12
And the children of Reuben, and the children of Gad, and half the tribe of Manasseh, passed over armed before the children of Israel, as Moses spake unto them:
Joshua 4:13
About forty thousand prepared for war passed over before the LORD unto battle, to the plains of Jericho.
Joshua 22:2-4
2
And said unto them, Ye have kept all that Moses the servant of the LORD commanded you, and have obeyed my voice in all that I commanded you:
3
Ye have not left your brethren these many days unto this day, but have kept the charge of the commandment of the LORD your God.
4
And now the LORD your God hath given rest unto your brethren, as he promised them: therefore now return ye, and get you unto your tents, and unto the land of your possession, which Moses the servant of the LORD gave you on the other side Jordan.
