'Puzzled' in the Bible

Now Herod the tetrarch heard about everything that was happening. He was puzzled because it was said by some that John had been raised from the dead,

All of them continued to be stunned and puzzled, and they kept asking one another, "What can this mean?"

I was puzzled how I should investigate such matters, so I asked if he would like to go to Jerusalem and be tried there for these things.
