The Foundling of the Nile was now formally brought up as the adopted son of Pharaoh’s daughter, and, in conformity with his high position, received a suitable education. He became _learned_, St Stephen tells us (Acts vii. 22), _in all the wisdom of the Egyptians_; in all therefore, we may believe, that the science of that day could teach him of arithmetic, writing, astronomy, medicine, and sacred symbolism. On the same authority we further learn that Moses became mighty not only _in words, but also in deeds_ (Acts vii. 22). What these _deeds_ were is not known[54], but it is certain that the Hebrew youth was in a position to have achieved a splendid career. He might have _enjoyed_ to the full _the pleasures_ of the Egyptian court (Heb. xi. 25), and amassed much of its accumulated treasures. But the traditions, the hopes, the creed of his own nation had not, we may believe, been concealed from him by his mother. Hence when he came to the age of forty, chancing to go forth from On or Memphis to the land of Goshen, he beheld one of his countrymen not only toiling amidst the shadeless brick-fields, but suffering the bastinado from his Egyptian taskmaster. Filled with indignation Moses _looked this way and that way_, and seeing no one by, slew the Egyptian, and hid the corpse in the white sand of the desert. The next day, seeing two of the Hebrews quarrelling, he tried to act as arbiter between them. His good offices, however, were not only rejected by the one he decided to be in the wrong, but he discovered that the murder of the Egyptian was no secret. He imagined that his countrymen would have recognised in him a Deliverer sent from the God of their fathers, but they did not. Before long, news of the murder reached the ears of Pharaoh, and Moses perceiving that his life was no longer safe fled from Goshen in a south-easterly direction to the land of Midian, or the peninsula of Sinai in Arabia, peopled by the descendants of Abraham by Keturah (Gen. xxv. 2).
