Following are a number of back-translations as well as a sample translation for translators of Judges 5:26:

• Kupsabiny: “(She) held in her left hand a tent peg,
  and had in the right hand a hammer.
  Jael crushed the head of Sisera,
  shattered it completely.
  (She) speared/stabbed with a tent peg through the temple,
  reaching through to the other side.” (Source: Kupsabiny Back Translation)
• Newari: “She took a nail in her hand,
  With the other hand [she] lifted a hammer,
  With the hammer she struck Sisera’s head,
  Sisera’s head was shattered.
  She pierced [it] with an iron nail,
  His head was pierced.” (Source: Newari Back Translation)
• Hiligaynon: “Then she took a hammer and tent peg and hammered-with-peg the head of Sisera, on the temple-of- his -head.” (Source: Hiligaynon Back Translation)
• English: “Then, when he was asleep, she reached for a tent peg with her left hand,
  and she reached for a hammer with her right hand.
  She hit Sisera hard with it and crushed his head.
