No. Desire is not a sin. You can desire without sinning, but you cannot lust after anything without sinning. Lust for money is greed. Lust for a married person is adultery of the heart. Yes, you can be angry or jealous without acting on those and sinning, but it is specifically stated in the Bible that to lust after another- just the mere dwelling on the subject, is sin.
Was Jesus angry with the money changers? Yes. Did He sin in His anger? No. He did make a whip out of ropes and use it on them though, and it's amazing that didn't land Him in jail.
Is God a jealous God? We disagree on this, so we're beating a dead horse. I can find no good in jealousy. It is a childish reaction. No good ever comes from jealousy any more than carrying anger in your heart, which is bad for you psychologically.
As I've stated, I was once angry and jealous when I found out my wife was cheating on me. What did it benefit me to be angry and jealous? NOTHING! Had I held onto that anger and jealousy it would have destroyed my life. Jealousy and anger eat at you like a cancer. I CHOSE to kick her to the curb, because both I, and my children who she abandoned, deserved better.
There are mistakes in the scriptures- things added that are inaccurate, like it or not. When I study the Bible and find something confusing, I compare it to the nature of the God that I serve. His nature is love. If what is written does not align with love, then it is a scripture or word that has been added by man, and it should not be there.
If you'd like, I can give you an example of a biblical mistake.
