Today's scripture is:
Joshua 1:12-15King James Version12 And to the Reubenites, and to the Gadites, and to half the tribe of Manasseh, spake Joshua, saying,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.
In this context we see Joshua reminding the Reubenites, Gadites, and the half tribe of Manasseh of the promise they made with Moses in Deuteronomy 3:18-20 (KJV):
Deuteronomy 3:18-20 (KJV)
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.
This shows us how we are supposed to help our fellow Christians once GOD has revealed something to us that helps us in our walk with HIM, we must share this with our brethren lest they continue in sin and we also sin by not showing them what GOD has freely shown us.
