Joshua

That by two immutable things, in which it was impossible for God to lie, we might have a strong consolation, who have fled for refuge to lay hold upon the hope set before us:

And they shall be unto you cities for refuge from the avenger; that the manslayer die not, until he stand before the congregation in judgment.

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

But if he thrust him suddenly without enmity, or have cast upon him any thing without laying of wait,

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.
