Proverbs 23:17
Do not let your heart envy sinners, but always be zealous for the fear of the LORD.

Envy (definition) : desire to have a quality, possession, or other desirable thing belonging to (someone else).

Do we envy sinners, wanting to have what they have? It is not advisable. (Proverbs 14:30) A heart at peace gives life to the body, but envy rots the bones.

When we are zealous for the fear of the LORD, then we may be free from envying sinners.

Application
