Two and a half of the tribes of Israel decided that they wanted to stay on the East side of the Jordan, and Moses rebuked them for it, thinking that they were not going to help conquer the land on the West side. However, they said to him,
Then they came near to him and said: “We will build sheepfolds here for our livestock, and cities for our little ones, but we ourselves will be armed, ready to go before the children of Israel until we have brought them to their place; and our little ones will dwell in the fortified cities because of the inhabitants of the land. We will not return to our homes until every one of the children of Israel has received his inheritance. For we will not inherit with them on the other side of the Jordan and beyond, because our inheritance has fallen to us on this eastern side of the Jordan” (Numbers 32.16–19).
The two and a half tribes had a plan; they would stay in the East and make preparations there, but they would lead the rest of Israel into the Land of Canaan. They kept their promise, and so they were able to keep their plan.
Make plans, and keep promises, and the Lord shall enable you to carry out your plans.
