There is a LOT happening in this verse. Paul is finally before a higher ruler, but clearly Festus is still present. Agrippa was Jewish but still a Roman ruler, and Paul even challenged him on his Jewish-ness (which could be seen as a bit of a challenge, maybe?). In the midst of this, his story is still of his conversion, of course including the detail of his work with some of the very men who were now accusing him. It's a mess. But Paul is still a witness to Jesus, though it looks very different than his usually preaching gigs. This is the faithfulness that we are also called to hold: to remain true to our call, no matter what form it may take.

(For this cycle through Psalms, I am departing from the NIV and reading from Robert Alter's "Hebrew Bible" translation.)
