Numbers 32:1-5 New International Version (NIV)
The Transjordan Tribes
32 The Reubenites and Gadites, who had very large herds and flocks, saw that the lands of Jazer and Gilead were suitable for livestock. 2 So they came to Moses and Eleazar the priest and to the leaders of the community, and said, 3 “Ataroth, Dibon, Jazer, Nimrah, Heshbon, Elealeh, Sebam, Nebo and Beon— 4 the land the Lord subdued before the people of Israel—are suitable for livestock, and your servants have livestock. 5 If we have found favor in your eyes,” they said, “let this land be given to your servants as our possession. Do not make us cross the Jordan.”
Moses assumed that there were selfish motives in avoiding crossing the river. He automatically assumed before getting all the facts. Have you ever assumed something before getting all the facts and before talking with the person you may be accusing of doing something? Try not to automatically assume that the motives are wrong. Take time to be objective and investigate. You will be glad you did.
