'Perplexity' in the Bible

And Herod the tetrarch heard of all the things which were done by him, and was in perplexity, because it was said by some that John was risen from among the dead,

And there shall be signs in the sun, and in the moon, and in the stars; and upon the earth distress of nations, with perplexity; the sea and the waves roaring;

And it came to pass as they were in perplexity about it, that behold, two men suddenly stood by them in shining raiment.
