I think you have a wise plan there.
I do have a fairly good study Bible but would love to find one for the Jerusalem Bible since it is used worldwide almost everywhere other than the U. S.
I also think that every person who teaches a Bible Study should have a concordance. I don’t take mine to class, but I always have it handy. Maybe I should change that, despite the weight of the book.
How about an electronic version? Not everything modern is bad ;-)
