It could be he sees you as a threat and is trying to ruin your reputation.

The first thing you have to do is never accept help from him. Accetping help from him will prove his poiint that he is better than you.

The next thing is to make him the laughingstock the next time he says something snide in your hearing and he will probably back off. Bullies tend to pester those who won't fight back.

The final thing is to preserve your own reputation by making sure you talk about your accomplishments to your boss and make sure you contribute in meetings or technical discussions in front of your peers. And make sure to do your tasks well and on-time and that others know this. It is much harder to ruin the reputaion of someone who is known to be doing a good job. This is office politics and playing well is critical to your career.

I'd bet you probably think that is it bad to play office politics, but really once someone starts in on you like this, you have no other choice except to leave as he may well be trying to get you fired for incompetence. He is playing the game and you are like a hockey goalie who isn't even trying to stop the other team from scoring. Whether you like it or not you are on the playing field and he may have chosen you to harrass in part becasue you don't play the game and thus are easy prey. Taking you out may be part of a greater plan to intimidate the others. You have to at least play defensive office politics to survive in the workplace.
