First you love your job. You want to keep it ...

I think this man is not very clever to tell this sort of thing to employee, but it shows you're a bit special, or different from the others there. Good for you of course. (as you love your job !).

You said these two employees are your friends, but friends since a few weeks ? and once they'll stop working there because it's the end of the contract maybe you'd never see them again ...??? Now it's different cause they'll have to leave before, but it's not your problem to tell them about it, this silly man didn't have to tell you, and you, you can't tell your 'friends' it's maybe too dangerous (if you want to keep your job). Maybe these friends don't really care of this job you know ...( Maybe you should ask ....)

Do you think it's possible that this man is trying to see if he can trust you, maybe he wants to know if you are going to tell your 'friends'. Cause more strange again, don't know why he did that, he certainly saw you're friends with these two others.
