Some very general databases (where you will find Journal articles) can help you find *many* results. If you are not sure what you want to focus on, this can be helpful to see what's out there.
Some specific, niche databases can help you find only the materials that focus on religious themes. You can use these databases to find more specific information on your topic. For instance, ATLA is an excellent resource that is focused on religion. You can search for a specific verse of the Bible and it will yield results including articles written on those verses.
