and profanation of the Sabbath, by which the sinner does no harm to another person, and which concern only his own principles, no person may be killed for the mere intention, if he has not carried it out.
It is known that desire is denounced because it leads to coveting, and the latter is prohibited because it leads to robbery, as has been said by our Sages.
The object of the law of restoring lost property to its owner (Deut. xxii. 1-3) is obvious. In the first instance, it is in itself a good feature in man's character. Secondly, its benefit is mutual; for if a person does not return the lost property of his fellow-man, nobody will restore to him what he may lose, just as those who do not honour their parents cannot expect to be honoured by their children.
A person who killed another person unknowingly must go into exile (Exod. xii. 13: Num. xxxv. 11-28); because the anger of "the avenger of the blood" (Num. xxxv. 19) cools down while the cause of the mischief is out of sight. The chance of returning from the exile depends on the death of [the high-priest], the most honoured of men, and the friend of all Israel. By his death the relative of the slain person becomes reconciled (ibid. ver. 25); for it is a natural phenomenon that we find consolation in our misfortune when the same misfortune or a greater one has befallen another person. Amongst us no death causes more grief than that of the high-priest.
The beneficial character of the law concerning "the breaking of the neck of a heifer" (Deut. xii. 1-8) is evident. For it is the city that is nearest to the slain person that brings the heifer, and in most cases the murderer comes from that place. The elders of the place call upon God as their witness, according to the interpretation of our Sages, that they have always kept the roads in good condition, have protected them, and have directed every one that asked his way; that the person has not been killed because they were careless in these general provisions, and they do not know who has slain him. As a rule the investigation, the procession of the elders, the measuring, and the taking of the heifer, make people talk about it, and by making the event public, the murderer may be found out, and he who knows of him, or has heard of him, or has discovered him by any clue, will now name the person that is the murderer, and as soon as a man, or even a woman or handmaid, rises up and names a certain person as having committed the murder, the heifer is not killed. It is well known that it is considered great wickedness and guilt on the part of a person who knows the murderer, and is silent about him whilst the elders call upon God as witness that they know nothing about the murderer. Even a woman will, therefore, communicate whatever knowledge she has of him. When the murderer is discovered, the benefit of the law is apparent. If the court of justice cannot sentence him to death, the king may find him guilty, who has the power to sentence to death on circumstantial evidence; and if the ling does not put him to death, the avenger of blood may scheme and plan his death, and at last kill him. We have thus shown the use of the law concerning the breaking of the neck of the heifer in discovering the murderer. Force is added to the law by the rule that the place in which the neck of the heifer is broken should never be cultivated or sown. The owner of the land will therefore use all means in his power to search and to find the murderer, in order that the heifer be not killed and his land be not made useless to him.
