These laws represent, in many ways, the high-water mark of Old Testament legislation. Every effort is made to eliminate that which experience had proved to be imperfect in the older laws and customs. The chief aim is to protect the rights of the wronged and dependent. The appeal throughout is not to the fear of punishment--in a large number of laws no penalty is suggested--but to the individual conscience. Not merely formal worship is demanded, but a love to God so personal that it dominates the individual heart and soul and finds expression through energies completely devoted to his service. These laws required strict justice, but more than that, mercy and practical charity toward the weak and needy and afflicted. Even the toiling ox and the helpless mother-bird and her young are not beyond the kin of these wonderful laws. Under their benign influence the divine principles of the prophets began to mould directly the character and life of the Israelitish race. The man who lives in accord with their spirit and injunctions to-day finds himself on the straight and narrow way, hallowed by the feet of the Master. IX INFLUENCES THAT GAVE RISE TO THE PRIESTLY LAWS AND HISTORIES [Sidenote: _Influences in the exile that produced written ceremonial laws_] The Babylonian exile gave a great opportunity and incentive to the further development of written law. While the temple stood, the ceremonial rites and customs received constant illustration, and were transmitted directly from father to son in the priestly families. Hence, there was little need of writing them down. But when most of the priests were carried captive to Babylonia, as in 597 B.C., and ten years later the temple was laid in ruins and all sacrifice and ceremonial worship suddenly ceased, written records at once became indispensable, if the customs and rules of Israel's ritual were to be preserved. The integrity and future of the scattered Israelitish race also largely depended upon keeping alive their distinctive traditions. Torn from their altars, the exiled priests not only had a strong incentive, but likewise the leisure, to write. The ritualistic zeal of their Babylonian masters doubtless further inspired them. The result was, that during the Babylonian exile and the following century most of the ceremonial laws in the Old Testament appear to have been first committed to writing. [Sidenote: _Ezekiel's Code_]
