Looks nice, good construction and good value
Color: Warm Gold
Looks nice, good construction and good value. Stays in place when tearing off sections of paper towels and looks more expensive than it was.

Bridging the Testaments
Format: Hardcover
Very scholarly and detailed if you want to know about the in depth history during this time period. Author is very knowledgeable & has done great research to present. He is very thorough! A lot of info. Helps you to truly comprehend all the various dynasties & kings & how they affected the Jews. Great resource book! I study Jewish history and am giving a sermon on the silent years. This helped me to understand this time period and how the various groups such as Sadducee's, Pharisees, Zealots, Hasidic, Essenes, publicans, etc began. That’s what I was searching for… when & how did these groups develop and splinter off? This book has answered these questions for me. Author writes so well & is organized in time periods! Great book!!

What a Reading Experience!
Format: Kindle
If your goal is to better grasp reading the New Testament, this book is the one for you! For me, it changed everything in my understanding of these Jewish groups that suddenly "appear" in Matthew when you turn the page from Malachi. Who were the Saducees? The Pharisees? Where did they come from? The Davidic loyalists? The Herodians? The Essenes? It was brilliantly documented with great charts tying history to specific scripture. It also sheds meaningful light also on the ongoing political intrigue of the middle east. Loved this book and highly recommend it.

Interesting coverage.
Format: Hardcover
Interesting recount of the history of Israel itself, and it’s relation to its neighbors during the period between the years covered by the Old and New Testaments.
