appears that for some time Moses was supported by his brother, and when this brother died, he earned a living by practising as a physician; but he never sought or derived any benefit from his services to his community, or from his correspondence or from the works he wrote for the instruction of his brethren; the satisfaction of being of service to his fellow-creatures was for him a sufficient reward.
The first public act in which Maimonides appears to have taken a leading part was a decree promulgated by the Rabbinical authorities in Cairo in the year 1167. The decree begins as follows — "In times gone by, when storms and tempests threatened us, we used to wander about from place to place but by the mercy of the Almighty we have now been enabled to find here a resting-place. On our arrival, we noticed to our great dismay that the learned were disunited; that none of them turned his attention to the needs of the congregation. We therefore felt it our duty to undertake the task of guiding the holy flock, of inquiring into the condition of the community, of "reconciling the hearts of the fathers to their children," and of correcting their corrupt ways. The injuries are great, but we may succeed in effecting a cure, and—in accordance with the words of the prophet— I will seek the lost one, and that which has been cast out I will bring back, and the broken one I will cure' (Micah iv. 6). When we therefore resolved to take the management of the communal affairs into our hands, we discovered the existence of a serious evil in the midst of the community," etc.
It was probably about that time that Maimon died. Letters of condolence were sent to his son Moses from all sides, both from Mohammedan and from Christian countries; in some instances the letters were several months on their way before they reached their destination.
The interest which Maimonides now took in communal affairs did not prevent him from completing the great and arduous work, the Commentary on the Mishnah, which he had begun in Spain and continued during his wanderings in Africa. In this Commentary he proposed to give the quintessence of the Gemara, to expound the meaning of each dictum in the Mishnah, and to state which of the several opinions had received the sanction of the Talmudical authorities. His object in writing this work was to enable those who are not disposed to study the Gemara, to understand the Mishnah, and to facilitate the study of the Gemara for those who are willing to engage in it. The commentator generally adheres to the explanations given in the Gemara, and it is only in cases where the halakah, or practical law, is not affected, that he ventures to dissent. He acknowledges the benefit he derived from such works of his predecessors as the Halakot of Alfasi, and the writings of the Geonim, but afterwards he asserted that errors which were discovered in his works arose from his implicit reliance on those authorities. His originality is conspicuous in the Introduction and in the treatment of general principles, which in some instances precedes the exposition of an entire section or chapter, in others that of a single rule. The commentator is generally concise, except when occasion is afforded to treat of ethical and theological principles, or of a scientific subject, such as weights and measures, or mathematical and astronomical problems. Although exhortations to virtue and warnings against vice are found in all parts of his work, they are especially abundant in the Commentary on Abot, which is prefaced by a separate
