It is said that the king of Egypt appointed him as one of his staff of physicians. The enlightened men of the kingdom were divided into seven grades, each grade occupying a corresponding position near the throne of the king on state occasions. The monarch considered Maimonides so much superior to the others that he made for him a special position. This, Moses, a modest man, declined. The other physicians, however, were jealous of his high standing, and being unable to injure him openly, they endeavored to accomplish his ruin in a secret manner.
