Numbers

Ye have heard that it was said by them of old time, Thou shalt not kill; and whosoever shall kill shall be in danger of the judgment:

Behold, thou hast driven me out this day from the face of the earth; and from thy face shall I be hid; and I shall be a fugitive and a vagabond in the earth; and it shall come to pass, that every one that findeth me shall slay me.

The revenger of blood himself shall slay the murderer: when he meeteth him, he shall slay him.

But 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:

Then said she, I pray thee, let the king remember the Lord thy God, that thou wouldest not suffer the revengers of blood to destroy any more, lest they destroy my son. And he said, As the Lord liveth, there shall not one hair of thy son fall to the earth.
