So, let's take a look at Nehemiah 7. Well, it's all about the rebuilding of Jerusalem, and the people are really getting into the spirit of it. So, the city walls are up and the gates are ready to go. But, apparently, the people had forgotten one key component: security! So, Nehemiah appoints a guard of officials to stand watch over the city, and to make sure that no one gets in who shouldn't. And, hey, if you thought the walls and gates were tough, wait 'til you hear about the guards! They were so tough that they even kept out the birds! So, if you're looking for a city that's secure, look no further than Jerusalem!
