OLD TESTAMENT
The Bible Project is a ministry based in Portland, Oregon that began several years ago making free Bible-based videos designed to bring a more complete understanding of the whole Bible and its unity. There Mission Statement says: Our mission is to show how the Bible is a unified story that leads to Jesus.
The Project has been very successful for several reasons: first, the quality of their production is notable, and second, they are reliable interpreters of the Word and have a solid grasp of theological concepts.
You can watch many of their videos on YouTube (their channel is here) or you can join their website here for free.
