Deuteronomy 21 1
My Notes Authors Matthew Henry - Commentary on the Whole Bible Care had been taken by some preceding laws for the vigorous and effectual persecution of a wilful murderer (ch. xix. 11, &c.), the putting of whom to death was the putting away of the guilt of blood from the land; but if this could not be done, the murderer not being discovered, they must not think that the land was in no danger of contracting any pollution because it was not through any neglect of theirs that the murderer was unpunished; no, a great solemnity is here provided for the putting away of the guilt, as an expression of their dread and detestation of that sin.
