Scott Stripling's The Trowel and the Truth: A Guide to Field Archaeology in the Holy Land gives readers a masterful treatment of the how and why of biblical archaeology. This book is important and timely for at least two reasons. First, archaeological work in the Holy Land continues to make good progress, resulting in exciting discoveries and fresh insights. Dr. Stripling's book informs readers of many of these recent and important discoveries. Secondly, archaeology greatly aids in the interpretation of Scripture. Few students, faculty, and pastors know the land of Israel and its rich treasures from the past as well as they should. Knowledge of the land and its archaeological insights will equip students, teachers, and pastors with important tools for better, sharper, more incisive interpretation of Scripture. Dr. Stripling's book shows how this can be done. The Trowel and the Truth guides readers through every essential aspect of archaeology.

Drs. Ralph Peil and Scott Stripling contend that God still uses the ancient device of covenant to offer amazing and life-changing levels of blessing, protection and provision. When everything else around is in ruin and chaos, covenant relationship with God is a lifeline.
This book is a beautifully-written explanation of the Biblical understandings of covenant. It is also moving personal testimonies by two men whose combined wisdom and insight are a rare treasure.
