Once again, I'm reading from The Book of Psalms: A Translation with Commentary. It's really good!

I rerecorded this episode a number of times, but I'll have you know it was not because of messing up Peter Piper! I also discovered there is an even better version of the nursery rhyme/tongue twister for showing the chiastic structure:

Now that I look at it, it's more like two chiasms with "Peter Piper picked" as the (A) parts and "a peck of pickled peppers" as the (B).
