All this is said by the chronicler to have taken place in accordance with The Law--"As it is written in the book of Moses."[65] Here, as in the case of the similar statement of the chronicler in connection with the sacrifices offered when the great altar of burnt-offerings was set up,[66] we must remember, in the first place, that we have to do with the reflections of an author writing in a subsequent age, to whom the whole Pentateuch was a familiar book. But then it is also clear that before Ezra had startled the Jews by reading The Law in its later revelation there must have been some earlier form of it, not only in Deuteronomy, but also in a priestly collection of ordinances. It is a curious fact that no full directions on the division of the courses of the priests and Levites is now to be found in the Pentateuch. On this occasion the services must have been arranged on the model of the traditional priestly law. They were not left to the caprice of the hour. There was order; there was continuity; there was obedience. [65] Ezra vi. 18. [66] Ezra iii. 2. The chronicler concludes this period of his history by adding a paragraph[67] on the first observance of the Passover among the returned Jews. The national religion is now re-established, and therefore the greatest festival of the year can be enjoyed. One of the characteristics of this festival is made especially prominent in the present observance of it. The significance of the unleavened bread is pointedly noticed. All leaven is to be banished from the houses during the week of the Passover. All impurity must also be banished from the people. The priests and Levites perform the ceremonial purifications and get themselves legally clean. The franchise is enlarged; and the limitations of genealogy with which we started are dispensed with. A new class of Israelites receives a brotherly welcome in this time of general purification. In distinction from the returned captives, there are now the Israelites who "had separated themselves unto them from the filthiness of the heathen of the land, to seek the Lord." Jehovah is pointedly described as "the God of Israel"--_i.e._, the God of all sections of Israel.[68] These people cannot be proselytes from heathenism--there could be few if any such in exclusive times. They might consist of Jews who had been living in Palestine all through the captivity, Israelites also left in the Northern Kingdom, and scattered members of the ten tribes from various regions. All such are welcome on condition of a severe process of social purging. They must break off from their heathen associations. We may suspect a spirit of Jewish animosity in the ugly phrase "the filthiness of the heathen." But it was only too true that both the Canaanite and the Babylonian habits of life were disgustingly immoral. The same horrible characteristic is found among most of the heathen to-day. These degraded people are not
