Blessed above women shall Jael be, The wife of Heber the Kenite; Blessed shall she be above women in the tent.
"Where he bowed, there he fell down dead"  (Judges 5:27).  This is a poetic reference to the fact that when Sisera collapsed from exhaustion in Jael's tent, that was the end of him.  It was the same as if he had fallen dead.  This is in no sense a contradiction of the account in  Judges 4, but the skillful addition of a number of pertinent details omitted in  Judges 4. This is characteristic of the Bible.  In all of the recapitulations we have studied, not one of them fails to add details not previously mentioned. This runs some scholars nearly crazy, but that is the way the Word of God is!
