Habakkuk 2:4 in Hebrews 10:38

I have decided to note new postings on Hebrews only once a week, but this past week Hebrews has not gotten much discussion in the blogosphere. Last week Brian Leport on his relatively new blog, Near Emmaus, has a brief discussion on the quotation of Habakkuk 2:4 in Hebrews 10:38.
