It has been maintained by some that the closing sentences of chap. xvii. should follow chap. xvi. with which they appear to be closely connected, the incident of the budding of Aaron's rod seeming to call rather for a festal celebration than a lament. The theory of the Book of Numbers we have seen reason to adopt would account for the introduction of the fresh episode, simply because it relates to the priesthood and tends to confirm the Aaronites in exclusive dignity. The symbolic test of the claim raised by the tribes corresponds closely to the signs that were used by some of the prophets, such as the girdle laid up by the river Euphrates, and the basket of summer fruits. The rod on which Aaron's name was written was of almond, a tree for which Syria was famous. Like the sloe it sends forth blossoms before the leaves; and the unique way in which this twig showed its living vigour as compared with the others was a token of the choice of Levi to serve and Aaron to minister in the holiest office before Jehovah. The whole circumstances, and the closing cry of the people, leave the impression of a grave difficulty found in establishing the hierarchy and centralising the worship. It was a necessity--shall we call it a sad necessity?--that the men of the tribes should be deprived of direct access to the sanctuary and the oracle. Earthly, disobedient, and far from trustful in God, they could not be allowed, even the hereditary chiefs among them, to offer sacrifices. The ideas of the Divine holiness embodied in the Mosaic law were so far in advance of the common thought of Israel, that the old order had to be superseded by one fitted to promote the spiritual education of the people, and prepare them for a time when there shall be "on the bells of the horses, HOLY UNTO THE LORD; and every pot in Judah shall be holy unto the Lord of hosts, and all they that sacrifice shall come and take of them and seethe therein." The institution of the Aaronic priesthood was a step of progress indispensable to the security of religion and the brotherhood of the tribes in that high sense for which they were made a nation. But it was at the same time a confession that Israel was not spiritual, was not the holy congregation Korah declared it to be. The greater was the pity that afterwards in the day of Israel's opportunity, when Christ came to lead the whole people into the spiritual liberty and grace for which prophets had longed, the priestly system was held tenaciously as the pride of the nation. When the law of ritual and sacrifice and priestly mediation should have been left behind as no longer necessary because the Messiah had come, the way of higher life was opened in vain. Sacerdotalism held its place with full consent of those who guided affairs. Israel as a nation was blinded, and its day shone in vain.
