Seeing this, the king and the princes knew that Moses had not acted with knowledge in taking the crown from off the king's head, and they refrained from slaying him.[65] God Himself, who protected Moses, turned the king's mind to grace, and his foster-mother snatched him away, and she had him educated with great care, so that the Hebrews depended upon him, and cherished the hope that great things would be done by him. But the Egyptians were suspicious of what would follow from such an education as his.[66] At great cost teachers were invited to come to Egypt from neighboring lands, to educate the child Moses. Some came of their own accord, to instruct him in the sciences and the liberal arts. By reason of his admirable endowments of mind, he soon excelled his teachers in knowledge. His learning seemed a process of mere recollecting, and when there was a difference of opinion among scholars, he selected the correct one instinctively, for his mind refused to store up anything that was false.[67] But he deserves more praise for his unusual strength of will than for his natural capacity, for he succeeded in transforming an originally evil disposition into a noble, exalted character, a change that was farther aided by his resolution, as he himself acknowledged later. After the wonderful exodus of the Israelites from Egypt, a king of Arabia sent an artist to Moses, to paint his portrait, that he might always have the likeness of the divine man before him. The painter returned with his handiwork, and the king assembled his wise men, those in particular who were conversant with the science of physiognomy. He displayed the portrait before them, and invited their judgment upon it. The unanimous opinion was that it represented a man covetous, haughty, sensual, in short, disfigured by all possible ugly traits. The king was indignant that they should pretend to be masters in physiognomy, seeing that they declared the picture of Moses, the holy, divine man, to be the picture of a villain. They defended themselves by accusing the painter in turn of not having produced a true portrait of Moses, else they would not have fallen into the erroneous judgment they had expressed. But the artist insisted that his work resembled the original closely.
