I have seen a few references to the number of imperatives in James. Most commentators say that there are over 50, so I scaned through the book and identified a list of 52 (below). I imagine there may be differences in how you count them. I used the imperative mood in the parsing to identify them. Three in chapter two are not actually addressed to the letter's recipient, but say what someone says.
I would be happy to have any errors or omissions pointed out. Leave a comment if you see something amiss.
