Deuteronomy 19:10
King James Version
“That innocent blood be not shed in thy land, which the LORD thy God giveth thee an inheritance, and blood be upon thee.”
Context
7Wherefore I command thee, saying, Thou shalt separate three cities for thee.
8And if the LORD thy God enlarge thy coast, as he hath sworn unto thy fathers, and give thee all the land which he promised to give unto thy fathers;
9If thou shalt keep all these commandments to do them, which I command thee this day, to love the LORD thy God, and to walk ever in his ways; then shalt thou add three cities more for thee, beside these three:
10That innocent blood be not shed in thy land, which the LORD thy God giveth thee an inheritance, and blood be upon thee.
11But if any man hate his neighbour, and lie in wait for him, and rise up against him, and smite him mortally that he die, and fleeth into one of these cities:
12Then 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.
13Thine eye shall not pity him, but thou shalt put away innocent blood from Israel, that it may go well with thee.
