[25] These frequent references do not prevent modern critics from affirming that the cities of refuge were no part of the Mosaic legislation. They found this view upon the absence throughout the history of all reference to them as being in actual use. They were not instituted, it is said, till after the Exile. But the very test that rejects them from the early legislation fails here. There is no reference to them as actually occupied in the post-exilian books, amounting, as these are said to do, to half the Old Testament. Their occupation, it is said, with the other Levitical cities, was postponed to the time of Messiah. The shifts to which the critics are put in connection with this institution do not merely indicate a weak point in their theory; they show also how precarious is the position that when you do not _hear_ of an institution as in actual operation you may conclude that it was of later date. Little needs to be said on the particular cities selected, except that they were conveniently dispersed over the country. Kedesh in Galilee in the northern part, Shechem in the central, and Hebron in the south, were all accessible to the people in these regions respectively; as were also, on the other side the river, Bezer in the tribes of Reuben, Ramoth in Gilead, and Golan in Bashan. Those who are fond of detecting the types of spiritual things in material, and who take a hint from Heb. vi. 18, connecting these cities with the sinner's refuge in Christ, naturally think in this connection of the nearness of the Saviour to all who seek Him, and the certainty of protection and deliverance when they put their trust in Him.
