Albert Barnes Commentary Deuteronomy 19:1-13

"When Jehovah thy God shall cut off the nations, whose land Jehovah thy God giveth thee, and thou succeedest them, and dwellest in their cities, and in their houses; thou shalt set apart three cities for thee in the midst of thy land, which Jehovah thy God giveth thee to possess it. Thou shalt prepare thee the way, and divide the borders of thy land, which Jehovah thy God causeth thee to inherit, into three parts, that every manslayer may flee thither. And this is the case of the manslayer, that shall flee thither and live: whoso killeth his neighbor unawares, and hated him not in time past; as when a man goeth into the forest with his neighbor to hew wood, and his hand fetcheth a stroke with the axe to cut down the tree, and the head slippeth from the helve, and lighteth upon his neighbor, so that he dieth; he shall flee unto one of these cities and live: lest the avenger of blood pursue the manslayer, while his heart is hot, and overtake him, because the way is long, and smite him mortally; whereas he was not worthy of death, inasmuch as he hated him not in time past. Wherefore I command thee, saying, Thou shalt set apart three cities for thee. And if Jehovah thy God enlarge thy border, as he hath sworn unto thy fathers, and give thee all the land which he promised to give unto thy fathers; if thou shalt keep all this commandment to do it, which I command thee this day, to love Jehovah thy God, and to walk ever in his ways; then shalt thou add three cities more for thee, besides these three: that innocent blood be not shed in the midst of thy land, which Jehovah thy God giveth thee for an inheritance, and so blood be upon thee. But if any man hate his neighbor, and lie in wait for him, and rise up against him, and smite him mortally so that he dieth, and he flee into one of these cities; then the elders of his city shall send and fetch him thence, and deliver him into the hand of the avenger of blood, that he may die. Thine eye shall not pity him, but thou shalt put away the innocent blood from Israel, that it may go well with thee." — Deuteronomy 19:1-13 (ASV)

This and the next two chapters contain enactments designed to protect human life, and to impress its sanctity on Israel.

In Deuteronomy 19:1-13, the directions respecting the preparation of the roads to the cities of refuge, the provision of additional cities in case of an extension of territory, and the intervention of the elders as representing the congregation, are unique to Deuteronomy and supplementary to the laws on the same subject given in the earlier books (compare the marginal reference).

Deuteronomy 19:1–2: The three cities of refuge for the district east of Jordan had already been named. Moses now directs that when the territory on the west of Jordan had been conquered, a similar allotment of three other cities in it should be made. This was accordingly done (compare Joshua 20:1 and following).

Deuteronomy 19:3: Thou shalt prepare thee a way — It was the duty of the Senate to repair the roads that led to the cities of refuge annually, and remove every obstruction. No hillock was left, no river over which there was not a bridge; and the road was at least 32 cubits broad. At crossroads, there were posts bearing the words "Refuge, Refuge," to guide the fugitive in his flight. It seems as if in Isaiah 40:3 and following the imagery were borrowed from the preparation of the ways to the cities of refuge.

Deuteronomy 19:5: With the axe — literally, “with the iron.” Note the employment of iron for tools, and compare Deuteronomy 3:11 note.

Deuteronomy 19:8–9: Provision is here made for the anticipated enlargement of the borders of Israel to the utmost limits promised by God, from the river of Egypt to the Euphrates (Genesis 15:18, note; Exodus 23:31, note). This promise, owing to the sins of the people, did not receive its fulfillment until after David had conquered the Philistines, Syrians, etc.; and this but a transient one, as many of the conquered peoples regained independence on the dissolution of Solomon’s empire.
