Adam Clarke on Acts 25:22

I would also hear the man myself - A spirit of curiosity, similar to that of Herod, Luk 23:8.

As Herod, the father of this Agrippa, had been so active an instrument in endeavoring to destroy Christianity, having killed James, and was about to have put Peter to death also, had not God sent him to his own place, there is no doubt that Agrippa had heard much about Christianity; and as to St. Paul, his conversion was so very remarkable that his name, in connection with Christianity, was known, not only throughout Judea, but through all Asia Minor and Greece. Agrippa, therefore might naturally wish to see and hear a man of whom he had heard so much.
