In Deuteronomy 19 we have the order in detail for the three cities of refuge, and then for three more, as in the early part of the book we saw the first set apart on the other side of the Jordan; for God on the one hand would mark the seriousness of blood-shedding; on the other, He would not confound a death at unawares with that which was deliberate murder. In no case however would God have His people to forget that it was His land, and consequently if blood were shed there, that it was thereby defiled. It called for serious thought. Man that was made in the image of God had his bloodshed there. God takes notice of it, but that which had a higher and a deeper reference requires not to be proved now. I have already dwelt upon it. Only take notice of the difference between the allusion here and in Numbers. There we saw it was applied especially to the blood-guilty while out of the land of their possession. Here is not a word said about the death of the priest that was anointed with the oil. The reason is manifest. The book of Deuteronomy applies to the people when they are just on the point of entering the land. Thus the insertions and omissions of the Spirit of God are as notable in the books of Moses as in the Gospels themselves. We may be more familiar with the idea and effect of design in the Gospels, but it is just as true here and everywhere else.
In Deuteronomy 19:12-13 the greatest care is enjoined to hinder all abuse through the cities of refuge. No facility must be given thereby for a murderer to find permanent shelter there. If blood was shed intentionally and deliberately, the elders of his city were bound to send and fetch him thence, delivering him over to the avenger of blood that he might die.
Then we find further care taken as to witnesses, and this affirmed by the great law of just retribution; that is to say, that when a witness testified what was deliberately false, and of course therefore malicious, the punishment which would have been adjudged in case of its truth was ordered to fall on him that raised the evil report. All this is carefully seen to. “And thine eye shall not pity; but life shall go for life, eye for eye, tooth for tooth, hand for hand, foot for foot.”
