Ok, so, I think I have found the
Greek AND
Hebrew origin but I'm not sure. IF I'm correct the Greek origin means in 'boiling with zeal'
Quote from another site: The primitive
Hebrew root which underpins the word 'Jealous' is qânâ' (
H7065). The meaning of it is
zealous,
jealous or
envious. The etymology of the word is disputed. Wilson believes it comes from being 'inflamed' or 'red' citing Schultens. Unger & White specifically disavow that derivation suggesting instead it means to be
'intensely competitive'.
The latter suggestion may well fit correctly with the first usage of the word although careful reading of the context is required to see this. The word first occurs in
Gen 26:14-
Gen 26:14 For he had possession of flocks, and possession of herds, and great store of servants: and the Philistines
envied him.
Gen 26:15 For all the wells which his father's servants had digged in the days of Abraham his father, the Philistines had stopped them, and filled them with earth.
At first glance this use of qânâ' rendered envied is simple material greed: Isaac had possessions which the Philistines would like. However verse 15 paints a different picture: the Philistines were not focused upon acquiring those possessions for themselves - they were focused to preventing Isaac's growth. It is quite possible that they wanted to prevent Isaac from growing too strong rather than growing stronger themselves. - End of quote
Soo that's all I got.
