When you saw two people walking together you could assume they had made a prior appointment. They had simply agreed to meet but the purpose of the meeting was not under consideration. They might have met to discuss their differences as they walked together. In our thickly populated areas one might easily run into an acquaintance and walk along with him. Amos did not live in such an area.
Nothing happens by chance.
There is a reason and a cause for Israel's calamities. We have rendered this passage in such a manner as to promote and defend schism and division among sincere brethren who could not conscientiously conform to the party norm. We have been betrayed into the false philosophy that doctrinal purity can be secured only by separation from brethren. If we continue this reckless course we will divide ourselves out of existence. I can walk together with those with whom I do not agree.
