Sirach 9:11

11 Envy not the glory of a sinner: for thou knowest not what shall be his end.

Sirach 9:11 In-Context

9 Sit not at all with another man's wife, nor sit down with her in thine arms, and spend not thy money with her at the wine; lest thine heart incline unto her, and so through thy desire thou fall into destruction.
10 Forsake not an old friend; for the new is not comparable to him: a new friend is as new wine; when it is old, thou shalt drink it with pleasure.
11 Envy not the glory of a sinner: for thou knowest not what shall be his end.
12 Delight not in the thing that the ungodly have pleasure in; but remember they shall not go unpunished unto their grave.
13 Keep thee far from the man that hath power to kill; so shalt thou not doubt the fear of death: and if thou come unto him, make no fault, lest he take away thy life presently: remember that thou goest in the midst of snares, and that thou walkest upon the battlements of the city.
