Abraham’s household comprised more than a thousand souls. Those who were led by his teachings to worship the one God, found a home in his encampment; and here, as in a school, they received such instruction as would prepare them to be representatives of the true faith. Thus a great responsibility rested upon him. He was training heads of families, and his methods of government would be carried out in the households over which they should preside. (PP 141.1) MC VC

In early times the father was the ruler and priest of his own family, and he exercised authority over his children, even after they had families of their own. His descendants were taught to look up to him as their head, in both religious and secular matters. This patriarchal system of government Abraham endeavored to perpetuate, as it tended to preserve the knowledge of God. It was necessary to bind the members of the household together, in order to build up a barrier against the idolatry that had become so widespread and so deep-seated. Abraham sought by every means in his power to guard the inmates of his encampment against mingling with the heathen and witnessing their idolatrous practices, for he knew that familiarity with evil would insensibly corrupt the principles. The greatest care was exercised to shut out every form of false religion and to impress the mind with the majesty and glory of the living God as the true object of worship. (PP 141.2) MC VC

It was a wise arrangement, which God Himself had made, to cut off His people, so far as possible, from connection with the heathen, making them a people dwelling alone, and not reckoned among the nations. He had separated Abraham from his idolatrous kindred, that the patriarch might train and educate his family apart from the seductive influences which would have surrounded them in Mesopotamia, and that the true faith might be preserved in its purity by his descendants from generation to generation.
