I'm not as enthusiastic about this one as about the previous two, though I do like the groomy dove. I may redo it. Let me know how you think it works.
I find this casting-of-lots thing interesting. Deuteronomy 18 forbids "divination," and casting lots sounds like divination to me, so that the sailors propose it seems to emphasize their non-Hebrewness and that Jonah agrees to it seems to emphasize (once again) that he is a pretty lousy Hebrew. He just won't do what God wants unless he has no other option. God's patience with him throughout this book may be unparalleled in the Bible.
