From the Writings and Utterances of `Abdu’l-Baha:
Among the great Prophets was Abraham, Who, being an iconoclast and a Herald of the oneness of God, was banished from His native land. He founded a family upon which the blessing of God descended, and it was owing to this religious basis and ordination that the Abrahamic house progressed and advanced. Through the divine benediction noteworthy and luminous prophets issued from His lineage. There appeared Isaac, Ishmael, Jacob, Joseph, Moses, Aaron, David and Solomon. The Holy Land was conquered by the power of the Covenant of God with Abraham, and the glory of the Solomonic wisdom and sovereignty dawned. All this was due to the religion of God which this blessed lineage established and upheld. It is evident that throughout the history of Abraham and His posterity this was the source of their honor, advancement and civilization. Even today the descendants of His household and lineage are found throughout the world.
(`Abdu’l-Baha: Promulgation of Universal Peace, p. 362)

Among the holy, divine Manifestations of God was His Holiness Moses. The sending of prophets has ever been for the training of humanity. They are the first educators and trainers. If Moses has developed the body-politic, there is no doubt that he was a true teacher and educator. This will be proof and evidence that he was a prophet. We shall consider how His Holiness was sent to despair, in the lowest degree of ignorance, and heedlessness, degraded and under conditions of bondage. His Holiness Moses rescued these degraded people of Israel from that state of bondage. He raised them from that condition of ignorance, saved them from barbarism and led them into the Holy Land. He educated them, endowed them with sagacious instincts, made them worthy and honorable. He civilized them, raised them to a higher plane of existence until they were enabled to establish a national sovereignty, the great kingdom of Solomon. This proves that His Holiness Moses was a teacher and an educator. He had neither army nor dominion, neither did he possess wealth. It was only through an idealistic power that he cemented them together proving that he was a prophet of God, an educator and trainer.
(`Abdu’l-Baha: Japan Will Turn Ablaze, pp. 44-45)

The children of Israel were in bondage and captivity in the land of Egypt four hundred years. They were in an extreme state of degradation and slavery under the tyranny and oppression of the Egyptians. While they were in the condition of abject poverty, in the lowest degree of abasement, ignorance and servility, Moses suddenly appeared among them. Although He was but a shepherd, such majesty, grandeur and efficiency became manifest in Him through the power of religion that His influence continues to this day. His Prophethood was established throughout the land, and the law of His Word became the foundation of the laws of the nations. This unique Personage, single and alone, rescued the children of Israel from bondage through the power of religious training and discipline. He led them to the Holy Land and founded there a great civilization which has become permanent and renowned and under which these people attained the highest degree of honor and glory. He freed them from bondage and captivity. He imbued them with qualities of progressiveness and capability. They proved to be a civilizing people with instincts toward education and scholastic attainment. Their philosophy became renowned; their industries were celebrated throughout the nations. In all lines of advancement which characterize a progressive people they achieved distinction. In the splendor of the reign of Solomon their sciences and arts advanced to such a degree that even the Greek philosophers journeyed to Jerusalem to sit at the feet of the Hebrew sages and acquire the basis of Israelitish law.
(`Abdu’l-Baha: Promulgation of Universal Peace, pp. 362-363)

Moses, for example, was sent forth to man and He established a Law, and the Children of Israel, through that Mosaic Law, were delivered out of their ignorance and came into the light; they were lifted up from their abjectness and attained to a glory that fadeth not.
(`Abdu’l-Baha: Selections … `Abdu’l-Baha, p. 52)

The Founder of monotheism was Abraham; it is to Him that this concept can be traced, and the belief was current among the Children of Israel, even in the days of Socrates.
(`Abdu’l-Baha: Selections … `Abdu’l-Baha, p. 55)

Know ye that the Torah is that which was revealed in the Tablets to Moses, may peace be upon Him, or that to which He was bidden. But the stories are historical narratives and were written after Moses, may peace be upon Him.
(`Abdu’l-Baha, quoted by the Universal House of Justice: Lights of Guidance, p. 501)

Journey of the Israelites :
It was both spiritual and physical. They journeyed to the Promised Land and geography and history both prove that this was a physical journey.
Moses viewed the Promised Land but died before it was reached, having given over his charge to Joshua.
The crossing of the Red Sea has a spiritual meaning. It was a spiritual journey, through and above the sea of corruption and iniquity of the Pharaoh and his people, or army. By the help of God through Moses, the Israelites were able to cross this sea safely and reach the Promised Land (spiritual state) while Pharaoh and his people were drowned in their own corruption.
(`Abdu’l-Baha: Lights of Guidance, p. 500)

After the Israelites had advanced along every level of civilization, and had achieved success in the highest possible degree, they began little by little to forget the root-principles of the Mosaic Law and Faith, to busy themselves with rites and ceremonials and to show forth unbecoming conduct. In the days of Rehoboam, the son of Solomon, terrible dissension broke out among them; one of their number, Jeroboam, plotted to get the throne, and it was he who introduced the worship of idols. The strife between Rehoboam and Jeroboam led to centuries of warfare between their descendants, with the result that the tribes of Israel were scattered and disrupted. In brief, it was because they forgot the meaning of the Law of God that they became involved in ignorant fanaticism and blameworthy practices such as insurgence and sedition. Their divines, having concluded that all those essential qualifications of humankind set forth in the Holy Book were by then a dead letter, began to think only of furthering their own selfish interests, and afflicted the people by allowing them to sink into the lowest depths of heedlessness and ignorance. And the fruit of their wrong doing was this, that the old-time glory which had endured so long now changed to degradation, and the rulers of Persia, of Greece, and of Rome, took them over.
(`Abdu’l-Baha: Secret of Divine Civilization, pp. 77-78)

At the time when the Israelites had been dispersed by the power of the Roman Empire and the national life of the Hebrew people had been effaced by their conquerors – when the law of God had seemingly passed from them and the foundation of the religion of God was apparently destroyed – Jesus Christ appeared. When He arose among the Jews, the first thing He did was to proclaim the validity of the Manifestation of Moses. He declared that the Torah, the Old Testament, was the Book of God and that all the prophets of Israel were valid and true. He extolled the mission of Moses, and through His proclamation the name of Moses was spread throughout the world. Through Christianity the greatness of Moses became known among all nations. It is a fact that before the appearance of Christ, the name of Moses had not been heard in Persia. In India they had no knowledge of Judaism, and it was only through the Christianizing of Europe that the teachings of the Old Testament became spread in that region. Throughout Europe there was not a copy of the Old Testament. But consider this carefully and judge it aright: Through the instrumentality of Christ, through the translation of the New Testament, the little volume of the Gospel, the Old Testament, the Torah, has been translated into six hundred languages and spread everywhere in the world. The names of the Hebrew prophets became household words among the nations, who believed that the children of Israel were, verily, the chosen people of God, a holy nation under the especial blessing and protection of God, and that, therefore, the prophets who had arisen in Israel were the daysprings of revelation and brilliant stars in the heaven of the will of God.
(`Abdu’l-Baha: Promulgation of Universal Peace, pp. 366-367)

Moreover, materially as well (as spiritually), the Israelites will gather in the Holy Land. This is irrefutable prophecy, for the ignominy which Israel has suffered for well-nigh twenty-five hundred years will now be changed into eternal glory, and in the eyes of all, the Jewish people will become glorified to such an extent as to draw the jealousy of its enemies and the envy of its friends.
(`Abdu’l-Baha: Lights of Guidance, p. 500)

From Letters Written on Behalf of Shoghi Effendi:
…If the Jews study the teachings they will find in them the hopes and aspirations that they have always cherished. Baha’u’llah bears a wonderful message to the Jews and many of them have come to appreciate it and are active in carrying it to others of their race. Through Baha’u’llah, the Master tells us, they shall regain their ancient glory and become loved by all the people of the whole world.
