Resources On Prayers To The Dead

We have collections of resources on the topic here and here, including many discussions of the patristic and other extrabiblical evidence. Jordan Cooper has been producing some videos on the subject that make many good points. See here, for example, and you can find more by running a search on YouTube. The Old Testament prohibitions of attempting to contact the dead tend to be neglected in these discussions. The passages either aren't brought up or get dismissed for inadequate reasons. Gary Smith has some helpful comments in the first volume of his Isaiah commentary, in his discussions of Isaiah 8:19 and 19:3 (Isaiah 1-39 [Nashville, Tennessee: B&H Publishing Group, 2007], 230-31, 357). The passages seem to be condemning all attempts to contact the dead, not merely certain forms of it, like going to a medium.
