 The people would eventually repent when the temples in their hearts came crashing down. And then they would cry out, revive us again, oh Lord. The again means that this was nothing new in their lives. They've done all this before. Hey Lord, we've blown this, but we're ready to change. You're different than all the other gods out there and you gave us salvation in the past. You've delivered us out of the hands of our enemies and our enemies are your enemies too.
