Resources on “Biblical Leadership”? Help!

I am doing some research on “Scriptural Models of Leadership” for a course and I discovered something unfortunate. There tends to be two kinds of written resources on this subject. Either you have proof-text-laden iso-getical popular fluff, or you find very specific material on one verse or Biblical figure.

What would you recommend a pastor read on the subject of “Biblical Leadership”?

There are only a handful of books on Biblical leadership that didn’t make my stomach churn. For the OT, I would recommend,

Laniak, T. Shepherds After My Own Heart: Pastoral Traditions and Leadership in the Bible (IVP, 2006)

Parks, L. and B.C. Birch, Ducking Spears, Dancing Madly: A Biblical Model of Church Leadership (Abingdon, 2004).

Stevens, M.E. Leadership Roles of the Old Testament: King, Prophet, Priest, Sage (Wipf & Stock, 2012).

For NT:

Ascough, R. and C.A. Cotton, Passionate Visionary: Leadership Lessons from the Apostle Paul (Hendrickson, 2006).

Clarke, A.D. Serve the Community of the Church: Christians as Leaders and Ministers (Eerdmans, 2000)

Agosto, E. Servant Leadership: Jesus and Paul (Chalice, 2005).

Tidball, D. Ministry by the Book: New Testament Patterns for Pastoral Leadership (IVP, 2009).

A good pan-Scriptural study is D. Howell’s Servants of the Servant: A Biblical Theology of Leadership (Wipf & Stock, 2003).

What did I miss?

While the above studies are all fine and good, this is a real need  – pastors could read loads of “leadership books,” but very few of the popular ones are based on a close reading of Scripture. I would appreciate your recommendations on this subject.
