I once heard a very interesting take on jealousy….The fellow said that if you are jealous you are doubting Hashem’s ability to
provide for you. It’s as if you are saying that because Hashem gave person A something, He is unable to provide for you. If you believe that Hashem “Hakol Yachol” then you needn’t be jealous. Hashem can provide you with whatever He deems you need!! Hope this thought helps.
