Please correct the above. Thanks.

1a. She feels jealous every time another woman looks at her boyfriend.
1b. She feels jealous if another woman looks at her boyfriend.
2a. Raman cast covetous eyes over Mohan’s new motorcycle. <-- Use of ‘cast…eyes’ is very old fashioned. Unlikely to be used in the western hemisphere. 3a is slightly less old fashioned because ‘jealous’ which is more common offsets the old-fashionedness of ‘cast… eyes’.
2b. Raman looked covetously at Mohan’s new motorcycle.
3a. Raman cast jealous eyes over Mohan’s new motorcycle.
3b. Raman looked jealously at Mohan’s new motorcycle. <-- This is the most natural of 2 and 3.

Beeesneees,

  1. Don’t be jealous of me. It is God given reward.
  2. Don’t envy me. It is God given reward.
    Are they OK? Thanks.

It is a God-given reward.
What does ‘it’ refer to?

Beeesneees,
‘It’ refers to my wealth.
Is it OK? Thanks.

Then you would need to explain that:
Don’t be jealous of me. My wealth is a God given reward.
Don’t envy me. My wealth is a God given reward.
