Verse 1-8 — The cities of the priests and Levites were not only to accommodate them, but to place them, as religious teachers, in several parts of the land. For though the typical service of the tabernacle or temple was only in one place, the preaching of the word of God, and prayer and praise, were not thus confined. These cities were to be given out of each tribe. Each thus made a grateful acknowledgement to God. Each tribe had the benefit of the Levites dwelling amongst them, to teach them the knowledge of the Lord; thus no parts of the country were left to sit in darkness. The gospel provides that he who is taught in the word, should communicate to him that teaches, in all good things, Galatians 6:6. We are to free God's ministers from distracting cares, and to leave them at leisure for the duties of their station; so that they may be wholly employed therein, and avail themselves of every opportunity, by acts of kindness, to gain the good-will of the people, and to draw their attention.
Verse 9-34 — To show plainly the abhorrence of murder, and to provide the more effectually for the punishment of the murderer, the nearest relation of the deceased, under the title of avenger of blood, (or the redeemer of blood,) in notorious cases, might pursue, and execute vengeance. A distinction is made, not between sudden anger and malice aforethought, both which are the crime of murder; but between intentionally striking a man with any weapon likely to cause death, and an unintentional blow. In the latter case alone, the city of refuge afforded protection. Murder in all its forms, and under all disguises, pollutes a land. Alas! that so many murders, under the name of duels, prize-fights, &c. should pass unpunished. There were six cities of refuge; one or other might be reached in less than a day's journey from any part of the land. To these, man-slayers might flee for refuge, and be safe, till they had a fair trial. If acquitted from the charge, they were protected from the avenger of blood; yet they must continue within the bounds of the city till the death of the high priest. Thus we are reminded that the death of the great High Priest is the only means whereby sins are pardoned, and sinners set at liberty. These cities are plainly alluded to, both in the Old and New Testament, we cannot doubt the typical character of their appointment. Turn ye to the strong hold, ye prisoners of hope, saith the voice of mercy,
