First, we note that the bones are described as either “dry” or “very dry.” (Ezek. 37:2, 11) This indicates that those to whom the bones belonged had been dead for a very long time. Second, the restoration is described as a gradual process, not something that happens suddenly. Initially, there was a noise, a rattling sound, and “the bones began to come together, bone to bone.” Then, “sinews and flesh” were added. Next, the bones, sinews, and flesh were covered with skin. Eventually, “breath came into them, and they began to live.” Finally, Jehovah settled the revived people on their land. All of this would take time.​—Ezek. 37:7-10, 14.

What about the second development, the restoration? When and how did that occur? This spiritual restoration work was a gradual process. It was accompanied by “a rattling sound” during the centuries leading up to the time of the end. Although false religious teachings held sway for the most part, some faithful individuals stood up in behalf of true worship to the extent that they were able to do so. Some of them endeavored to produce Bibles in the languages of the common people. Others declared the truths that they had discovered in the pages of God’s Word.
