'Taker' in the Bible

You are to make ready a way, and see that the land which the Lord your God is giving you for your heritage, is marked out into three parts, to which any taker of life may go in flight.

For if not, he who has the right of punishment may go running after the taker of life in the heat of his wrath, and overtake him because the way is long, and give him a death-blow; though it is not right for him to be put to death because he was not moved by hate.
