I am reading through the Bible with a group of people from the Church I lead. One resource that I am always recommending to them is https://bibleproject.com/

There are lots of resources on this site, and I have not been able to explore them all. One thing I repeatedly recommend is to click on the tab at the top labeled “Watch.” Then go to “Old Testament Overviews” or “New Testament Overviews.” Finally, click on the book you are starting to read, and you will be able to watch an animated overview that helps you gain an understanding of the background and setting. 

These videos are particularly beneficial with the Old Testament prophets and any books with which you are not familiar.
