"9 And the Lord spoke to Moses, saying, 10 “Speak to the people of Israel and say to them, When you cross the Jordan into the land of Canaan, 11 then you shall select cities to be cities of refuge for you, that the manslayer who kills any person without intent may flee there. 12 The cities shall be for you a refuge from the avenger, that the manslayer may not die until he stands before the congregation for judgment. 13 And the cities that you give shall be your six cities of refuge. 14 You shall give three cities beyond the Jordan, and three cities in the land of Canaan, to be cities of refuge. 15 These six cities shall be for refuge for the people of Israel, and for the stranger and for the sojourner among them, that anyone who kills any person without intent may flee there.
16 “But if he struck him down with an iron object, so that he died, he is a murderer. The murderer shall be put to death. 17 And if he struck him down with a stone tool that could cause death, and he died, he is a murderer. The murderer shall be put to death. 18 Or if he struck him down with a wooden tool that could cause death, and he died, he is a murderer. The murderer shall be put to death. 19 The avenger of blood shall himself put the murderer to death; when he meets him, he shall put him to death. 20 And if he pushed him out of hatred or hurled something at him, lying in wait, so that he died, 21 or in enmity struck him down with his hand, so that he died, then he who struck the blow shall be put to death. He is a murderer. The avenger of blood shall put the murderer to death when he meets him.
22 “But if he pushed him suddenly without enmity, or hurled anything on him without lying in wait 23 or used a stone that could cause death, and without seeing him dropped it on him, so that he died, though he was not his enemy and did not seek his harm, 24 then the congregation shall judge between the manslayer and the avenger of blood, in accordance with these rules. 25 And the congregation shall rescue the manslayer from the hand of the avenger of blood, and the congregation shall restore him to his city of refuge to which he had fled, and he shall live in it until the death of the high priest who was anointed with the holy oil. 26 But if the manslayer shall at any time go beyond the boundaries of his city of refuge to which he fled, 27 and the avenger of blood finds him outside the boundaries of his city of refuge, and the avenger of blood kills the manslayer, he shall not be guilty of blood. 28 For he must remain in his city of refuge until the death of the high priest, but after the death of the high priest the manslayer may return to the land of his possession. 29 And these things shall be for a statute and rule for you throughout your generations in all your dwelling places.
30 “If anyone kills a person, the murderer shall be put to death on the evidence of witnesses. But no person shall be put to death on the testimony of one witness. 31 Moreover, you shall accept no ransom for the life of a murderer, who is guilty of death, but he shall be put to death. 32 And you shall accept no ransom for him who has fled to his city of refuge, that he may return to dwell in the land before the death of the high priest. 33 You shall not pollute the land in which you live, for blood pollutes the land, and no atonement can be made for the land for the blood that is shed in it, except by the blood of the one who shed it. 34 You shall not defile the land in which you live, in the midst of which I dwell, for I the Lord dwell in the midst of the people of Israel."
Numbers 35:9-34
The distinction between the murderer and the manslayer has its parallel in the gospel, although some little thought has to be given to it to understand it aright and appreciate it fully. There was no mercy, no provision for the murderer, in the Old Testament. He was to be put to death, for his crime was deliberate and premeditated. The question that therefore arises is what parallel there is in the New Testament, with the sinner. For is not our sin also deliberate? Ah, yes; but human sin is rarely pure deliberation, but most often admixed with something else with ignorance, weakness and frailty. One recalls what Jesus said of those who crucified Him: 'Father, forgive them, for they know not what they do'. They knew very well, in one sense; but in another, their deliberate malice and hatred were mixed with blindness and ignorance. What Paul says of himself to Timothy, 'I obtained mercy, because I did it ignorantly and in unbelief' is another instance of the same thought. His sin in persecuting the Church was deliberate enough, but it was also mixed with something else: he was duped by the god of this world. And for this reason, mercy was possible for him. It is only when sin is purely de- liberate and therefore demonic that there is no possibility of forgiveness. Then, the point of no return has been passed; it is the sin unto death, the 'presumptuous sin' of the Old Testament, the 'great transgression' which banishes a man from the presence of God forever.
