It was one of the precepts given to the sons of Noah that whoso sheddeth man's blood by man shall his blood be shed, that is, by the avenger of blood, Gen 9:6. Now here we have the law settled between blood and blood, between the blood of the murdered and the blood of the murderer, and effectual provision made,

I.That the cities of refuge should be a protection to him that slew another casually, so that he should not die for that as a crime which was not his voluntary act, but only his unhappiness. The appointment of these cities of refuge we had before (Exo 21:13), and the law laid down concerning them at large, Num 35:10, etc. It is here repeated, and direction is given concerning three things: -

1.The appointing of three cities in Canaan for this purpose. Moses had already appointed three on that side Jordan which he saw the conquest of; and now he bids them, when they should be settled in the other part of the country, to appoint three more, Deu 19:1-3, Deu 19:7. The country was to be divided into three districts, as near by as might be equal, and a city of refuge in the centre of each so that every corner of the land might have one within reach. Thus Christ is not a refuge at a distance, which we must ascend to heaven or go down to the deep for, but the word is nigh us, and Christ in the word, Rom 10:8. The gospel brings salvation to our door, and there it knocks for admission. To make the flight of the delinquent the more easy, the way must be prepared that led to the city of refuge. Probably they had causeways or street-ways leading to those cities, and the Jews say that the magistrates of Israel, upon one certain day in the year, sent out messengers to see that those roads were in good repair, and they were to remove stumbling-blocks, mend bridges that were broken, and, where two ways met, they were to set up a Mercurial post, with a finger to point the right way, on which was engraven in great letters, Miklat, Miklat - Refuge, Refuge. In allusion to this, gospel ministers are to show people the way to Christ, and to assist and direct them in flying by faith to him for refuge. They must be ready to remove their prejudices, and help them over their difficulties. And, blessed be God, the way of holiness, to all that seek it faithfully, is a highway so plain that the wayfaring men, though fools, shall not err therein.

2.The use to be made of these cities, Deu 19:4-6. (1.) It is supposed that it might so happen that a man might be the death of his neighbour without any design upon him either from a sudden passion or malice prepense, but purely by accident, as by the flying off of an axe-head, which is the instance here given, with which every case of this kind was to be compared, and by it adjudged. See how human life lies exposed daily, and what deaths we are often in, and what need therefore we have to be always ready, our souls being continually in our hands. How are the sons of men snared in an evil time, when it falls suddenly upon them! Ecc 9:12. An evil time indeed it is when this happens not only to the slain but to the slayer. (2.) It is supposed that the relations of the person slain would be forward to avenge the blood, in affection to their friend and in zeal for public justice. Though the law did not allow the avenging of any other affront or injury with death, yet the avenger of blood, the blood of a relation, shall have great allowances made for the heat of his heart upon such a provocation as that, and his killing only, should not be accounted murder if he did it before he got to the city of refuge, though it is owned he was not worthy of death. Thus would God possess people with a great horror and dread of the sin of murder: if mere chance-medley did thus expose a man, surely he that wilfully does violence to the blood of any person, whether from an old grudge or upon a sudden provocation, must flee to the pit, and let no man stay him (Pro 28:17); yet the New Testament represents the sin of murder as more heinous and more dangerous than even this law does. Jo1 3:15, You know that no murderer has eternal life abiding in him. (3.) It is provided that, if an avenger of blood should be so unreasonable as to demand satisfaction for blood shed by accident only, then the city of refuge should protect the slayer. Sins of ignorance indeed do expose us to the wrath of God, but there is relief provided, if by faith and repentance we make use of it. Paul that had been a persecutor obtained mercy, because he did it ignorantly; and Christ prayed for his crucifiers, Father, forgive them, for they know not what they do.

3.The appointing of three cities more for this use in case God should hereafter enlarge their territories and the dominion of their religion, that all those places which came under the government of the law of Moses in other instances might enjoy the benefit of that law in this instance, Deu 19:8-10. Here is, (1.) An intimation of God's gracious intention to enlarge their coast, as he had promised to their fathers, if they did not by their disobedience forfeit the promise, the condition of which is here carefully repeated, that, if it were not performed, the reproach might lie upon them, and not on God. He promised to give it, if thou shalt keep all these commandments; not otherwise. (2.) A direction to them to appoint three cities more in their new conquests, which, the number intimates, should be as large as their first conquests were; wherever the border of Israel went this privilege must attend it, that innocent blood be not shed, Deu 19:10. Though God is the saviour and preserver of all men, and has a tender regard to all lives, yet the blood of Israelites is in a particular manner precious to him, Psa 72:14. The learned Ainsworth observes that the Jewish writers themselves own that, the condition not being performed, the promise of the enlarging of their coast was never fulfilled; so that there was no occasion for ever adding these three cities of refuge; yet the holy blessed God (say they) did not command it in vain, for in the days of Messiah the prince three other cities shall be added to these six: they expect it to be fulfilled in the letter, but we know that in Christ it has its spiritual accomplishment, for the borders of the gospel Israel are enlarged according to the promise, and in Christ, the Lord our righteousness, refuge is provided for those that by faith flee to him.

II.It is provided that the cities of refuge should be no sanctuary or shelter to a wilful murderer, but even thence he should be fetched, and delivered to the avenger of blood, Deu 19:11-13. 1. This shows that wilful murder must never be protected by the civil magistrate; he bears the sword of justice in vain if he suffers those to escape the edge of it that lie under the guilt of blood, which he by office is the avenger of. During the dominion of the papacy in our own land, before the Reformation, there were some churches and religious houses (as they called them) that were made sanctuaries for the protection of all sorts of criminals that fled to them, wilful murderers not excepted, so that (as Stamford says, in his Pleas of the Crown, lib. II. c. 38) the government follows not Moses but Romulus, and it was not till about the latter end of Henry VIII's time that this privilege of sanctuary for wilful murder was taken away, when in that, as in other cases, the word of God came to be regarded more than the dictates of the see of Rome. And some have thought it would be a completing of that instance of reformation if the benefit of clergy were taken away for man-slaughter, that is, the killing of a man upon a small provocation, since this law allowed refuge only in case of that which our law calls chance-medley. 2. It may be alluded to to show that in Jesus Christ there is no refuge for presumptuous sinners, that go on still in their trespasses. If we thus sin wilfully, sin and go on in it, there remains no sacrifice, Heb 10:26. Those that flee to Christ from their sins shall be safe in him, but not those that expect to be sheltered by him in their sins. Salvation itself cannot save such: divine justice will fetch them even from the city of refuge, the protection of which they are not entitled to.

Thou shalt not remove thy neighbour's landmark,.... By which one man's land is distinguished from another; for so to do is to injure a man's property, and alienate his lands to the use of another, which must be a very great evil, and render those that do it obnoxious to a curse, Deu 27:17.

which they of old have set in thine inheritance, which thou shall inherit in the land that the Lord thy God giveth thee to possess it; the land of Canaan: this is thought to refer to the bounds and limits set in the land by Eleazar and Joshua, and those concerned with them at the division of it; when not only the tribes were bounded; and distinguished by certain marks, but every man's estate, and the possession of every family in every tribe which though not as yet done when this law was made, yet, as it respects future times, might be said to be done of old, whenever there was any transgression of it, which it cannot be supposed would be very quickly done; and it is a law not only binding on the inhabitants of the land of Canaan, but all others, it being agreeably to the light and law of nature, and which was regarded among the Heathens, Pro 22:28.

And if the Lord thy God enlarge thy coast--Three additional sanctuaries were to be established in the event of their territory extending over the country from Hermon and Gilead to the Euphrates (see Gen 15:18; Exo 23:31). But it was obscurely hinted that this last provision would never be carried into effect, as the Israelites would not fulfil the conditions, namely, "that of keeping the commandments, to love the Lord, and walk ever in his ways." In point of fact, although that region was brought into subjection by David and Solomon, we do not find that cities of refuge were established; because those sovereigns only made the ancient inhabitants tributary, instead of sending a colony of Israelites to possess it. The privilege of sanctuary cities, however, was given only for Israelites; and besides, that conquered territory did not remain long under the power of the Hebrew kings.
