Defend - The marginal reading “to deliver,” is far preferable. The word is the same as in Jdg 2:16, Jdg 2:18; Jdg 3:9, Jdg 3:15, Jdg 3:31, etc., and is the technical word applied to the judges. Compare Neh 9:27 (“saviours who saved them,” the King James Version).
The term “there arose,” also marks Tola as one of the Judges, properly so called, raised by divine providence.
Tola and Puah - Both names of heads of houses in the tribe of Issachar 1Ch 7:1; Gen 46:13.
Shamir - Not the same as that mentioned in Jos 15:48, which was in the hill country of Judah. Issaehar would seem from this to have extended into the northern part of mount Ephraim.
