This article discusses the matter of the double portion in Deuteronomy 21:15-17, and whether it is still in force today. The author argues it is not, as the entire system regarding firstborn laws seems to have been typological.

Looking at the relationship between Deuteronomy 21:23 and Galatians 3:13, this article shows how Christ fulfilled the text of Deuteronomy through the crucifixion. The author shows how Christ's fulfillment of the law and His obedience to the point of being hung on a tree contrasts with Adam's disobedience of eating from the tree.
