Other than several new book reviews and the appearance of two new articles, Hebrews has gotten scant attention among the biblioblogs in the month of April:
Continuing from March, Ken Schenck has additional thoughts on Hebrews 4:14–13:25. Ken also has a post on Hebrews - Sermon to a Struggling Church.
James McGrath comments on the phrase, "tempted in every way as we are" in Hebrews 4:15.
William Mounce discusses Ransom and Redemption in Heb 9:15.
