Were you using the second passport to leave Malta, or to enter Israel?

To leave Malta. I was interrogated by a member of Israel Defense Forces, though.

I always wondered if this would get flagged somehow. I've never tried it myself, but I've thought about doing it.

What I was mentioning though is that countries will let you have a second passport from a single country if you have issues like this, to avoid showing the stamps in one passport.
