Query: wonderful book

Like pretty much all of Dr. Barclay's books, the Letter to the Hebrews makes the Bible verses that are so difficult to comprehend easy to understand and beautiful. His Bible studies are good whether you're reading the Bible for the first time or whether you're studying it in depth. He gives you a lot of historical background which really helps. I did find the section about priesthood (Hebrews chapter 7) slightly tedious, but that's my only complaint. It's definitely a worth while read.
