Deuteronomy 3:18-20 - 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. 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; 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.
And now, admonition.
Deuteronomy chapter three verse 18 we read, hen I commanded you at that time, saying the Lord your God has given you all this land to possess. All you men of Valor shall cross over armed before your brethren, the children of Israel, but your a wives, your little ones and your livestock, I know that you have much livestock, shall stay in your cities, which I have given you, until the Lord has given arrest to your brother and as to you. God tells the two and a half tribes that will stay and live on the other side of the Jordan River, You don't get to stay over here while your brethren go and fight to take the Promised Land that I promised to you.
We need to learn to prioritize others above ourselves. We need to learn that when others are still working, are still laboring. We don't need to be sitting back doing nothing. We need to be helping our brethren in the work.
