As to the contents of the Law which thus gradually took form, a distinction may easily be traced even by the cursory reader. The earlier code, Deuteronomy, is full of a generous and lofty temper. It is one of the most impressive documents of the Jewish scriptures. Here is that which Jesus named as the first and great commandment: "Thou shalt love the Lord thy God with all thy heart, and with all thy soul, and with all thy might." The teaching of the book is primarily the worship of Yahveh,--a holy, loving, and judging God,--who rewards his people with blessings or punishes them with disasters. Promises and threats are equally distinct and vivid: never were blessing and cursing more emphatic. The morality enjoined is charitable and pure. With an equal insistence is enjoined a certain method and form of worship, including sacrifices at the temple, three yearly feasts, the observance of the Sabbath, the due maintenance of the priesthood, and the utter rejection of all other gods. When we turn to the other books of the Law, we come into an atmosphere less exalted, and with a multiplicity of ceremonial details. There is endless regulation as to varieties of sacrifice, cleansing from technical uncleanness, and the like. Interwoven with these, as if on an equal footing, are special applications of morality--inculcations of chastity, justice, and good neighborhood. The principles of the Ten Words--themselves an inheritance from a very early day--are applied in many particulars. Occasionally is a lofty sentiment, a clear advance. Thus we find in Leviticus the "second commandment" of Jesus, "Thou shalt love thy neighbor as thyself." The general increase in rigidity of ceremonial in these books is to be read along with the stern decrees of Ezra as to separation from family and friendly relations with non-Jewish neighbors. It was, in a word, a Puritan reformation. There was just the same combination of heightened moral conviction with urgency upon matters of form and detail, and hostility to all outside of one special church, which belonged to the Puritan. But the Jewish reformer, unlike the English, enlarged instead of simplifying his ritual. It is this interblending of outward observance with moral and spiritual quality which stumbles the modern reader at every page. It was a confusion which needed the spiritual genius of Jesus to dissolve, and the leadership of Paul to definitely renounce.
