After four chapters devoted to the history of and repercussions flowing from the life of a single judge (Gideon), we come to a chapter in which the entire life’s work of two judges (Tola and Jair) and the manner in which they each delivered their nation are summed up in a mere five verses. Thirteen more are devoted to setting up the story of the next judge (Jephthah). Sixty-four years covered in eighteen verses.
We might view the relative brevity of these next two accounts as an imbalance of sorts, especially if we are used to reading secular history.
