Context / meaning
Deuteronomy 19 [10.] This is so that innocent blood will not be shed in the middle of your land which Yahweh your God gives you for an inheritance, leaving blood guilt on you. But if any man hates his neighbor, lies in wait for him, rises up against him, strikes him mortally so that he dies, and he flees into one of these cities; then the elders of his city shall send and bring him there, and deliver him into the hand of the avenger of blood, that he may die. Your eye shall not pity him, but you shall purge the innocent blood from Israel, that it may go well with you. You shall not remove your neighbor’s landmark, which they of old time have set, in your inheritance which you shall inherit, in the land that Yahweh your God gives you to possess.
Deuteronomy 19 [15.] One witness shall not rise up against a man for any iniquity, or for any sin, in any sin that he sins. At the mouth of two witnesses, or at the mouth of three witnesses, shall a matter be established. If an unrighteous witness rises up against any man to testify against him of wrongdoing, then both the men, between whom the controversy is, shall stand before Yahweh, before the priests and the judges who shall be in those days; and the judges shall make diligent inquisition: and, behold, if the witness is a false witness, and has testified falsely against his brother; then you shall do to him as he had thought to do to his brother. So you shall remove the evil from among you.
Deuteronomy 19 [20.] Those who remain shall hear, and fear, and will never again commit any such evil among you.
