The fruit of the righteous is a tree of life, and the one who is wise saves lives.
OJBThe p'ri tzedek is Etz Chayyim, and he that winneth nefashot is chacham (wise).
T4TThose who live righteously will live for a long time, but those who act violently will destroy their own lives (OR, those who are wise will have many people come and live with them).
