By means of the following incident God showed Moses how little man is able to fathom the inscrutable ways of the Lord. When Moses was on Sinai, he saw from that station a man who betook himself to a river, stooped down to drink, lost his purse, and without noticing it went his way. Shortly after, another man cam, found the money, pocketed it, and took to his heels. When the owner of the purse became aware of his loss, he returned to the river, where he did not find his money, but saw a man, who came there by chance to fetch water.
To him he said: "Restore to me the money that a little while ago I left here, for none can have taken it if not thou." When the man declared that he had found none of the money nor seen any of it, the owner slew him. Looking with horror and amazement on this injustice on earth, Moses said to God: "I beseech Thee, show my Thy ways. Why has this man, who was quite innocent, been slain, and why hath the true thief gone unpunished?"
God replied: "The man who found the money and kept it merely recovered his own possession, for he who had lost the purse by the river, had formerly stolen it from him; but the one who seemed to be innocently slain is only making atonement for having at one time murdered the father of his slayer." In this way, God granted the request of Moses, "to show him His ways," in part only. He let him look into the future, and let him see every generation and it sages, every generation and its prophets, every generation and its expounders of the Scriptures, every generation and its leaders, ever generation and its pious men.
But when Moses said: "O Lord of the world! Let me see by what law Thou dost govern the world; for I see that many a just man is lucky, but many a one is not; many a wicked man is lucky, but many a one is not; many a rich man is happy, but many a one is not; many a poor man is happy, but many a one is not;" then God answered: "Thou canst not grasp all the principles which I apply to the government of the world, but some of them shall I impart to thee.
When I see human beings who have no claim to expectations from Me either for their own deeds or for those of their fathers, but who pray to Me and implore Me, then do I grant their prayers and give them what they require from subsistence."
