Although, at the time at which Abraham is said to have lived, the knowledge of an abstract dual or triune God still remained, yet, during the five hundred years which elapsed until the time of Moses, the grossest idolatry had come to prevail. Notwithstanding the fact that Moses had learned much from the Egyptians, he seems not to have risen above a very gross conception of a deity. His god was by turns angry, jealous, revengeful, vacillating, and weak. He was in fact the embodiment of human passions and desires. We have seen that the third person in the ancient Trinity had, in Egypt, India, and Persia, come to be recognized in place of the three principles originally worshipped--that, as it really embodied the essence of the other two, little was heard of the Creator and Preserver. Doubtless this God was the one which Moses intended the Israelites to worship, but as they were unable to conceive of an abstract principle he invested it with a personality which, as we have seen, was burdened with the frailties and weaknesses common to themselves. As the Regenerator or Destroyer represented the processes of Nature,--the dying away of the sun's rays at night only to reappear on the following day, and the withdrawal of its warmth in winter only to be renewed in the spring,--so this God portrayed also the beneficent Creator and Preserver of all things, at the same time that it was the Destroyer. It embodied the fundamental idea in all religions, namely, life and fertility. So also did the "Lord" of the Israelites represent reproductive energy, but as man being spirit had come to be a Creator of offspring, while woman being only matter furnished the body, this "Lord" was male. Connected with it was no hint of the female nature or principle, except the ark or chest in which it was carried about. To those who have acquainted themselves with the significance of ancient religious symbols, the fact is plain that the "Lord" of the Israelites, which in their journeyings toward Canaan they carried in an ark or chest, and which was symbolized by an upright stone, was none other than a "Life-giver" in the most practical sense. It was the emblem of virility, and from the facts at hand, at the present time, there is little doubt but that all the spirituality with which we find this "Lord" invested was an after-thought and comprehended no part of the belief of the Jews until after their contact with the Persians during the Babylonian captivity.
