Score! The entire Interpreter's Bible series came into my thrift store the other day, all twelve volumes. Now... to be fair, I didn't purchase them for myself immediately. I left them on the sales floor for a couple of days. But when nobody else seemed interested, I snatched them up. At a dollar per volume, I call it a win.
Published by United Methodist Publishing (Abingdon / Cokesbury ) in the 1950s, they include general articles about biblical studies, introductions to each book, commentary and critical notes.
I also have The Interpreter's One Volume Commentary on the Bible. My dad gave it to me before I went to the Salvation Army Training College (seminary). I also have one volume of the New Interpreter's Bible series, an updated version of the series published in the 1990s.
