Following are a number of back-translations as well as a sample translation for translators of Judges 20:36:

• Kupsabiny: “Then, the people of the clan of Benjamin saw/realized that their soldiers had been defeated.
  And how the battle was is like this: The people of Israel pretended to flee so as to give opportunity for their people who had hid themselves to go and take the city of Gibeah.” (Source: Kupsabiny Back Translation)
• Newari: “Then the Benjaminites knew [it]: "We are defeated."
  All the Israelites, trusting the men who were in hiding out around [lit.: before] Gibeah, acted like they were [being] defeated.” (Source: Newari Back Translation)
• Hiligaynon: “And the Benjaminhon realized that they were now defeated.
  The big group of the soldiers of Israel fled so-that the soldiers they were-having-besiege the city of Gibea could-attack.” (Source: Hiligaynon Back Translation)
• English: “The main group of Israeli men arranged with the men who would be hiding that they should send up a smoke signal to enable the main group of soldiers to know when they should attack. Then the main group of Israeli men retreated for a short distance, because they knew that the other Israeli men who had been hiding on the other side of Gibeah would attack the people of the tribe of Benjamin by surprise. So after the main group of Israeli men retreated a little distance, the men who had been hiding rushed out and ran into Gibeah and used their swords to kill everyone in the city. Then they started to burn the buildings.” (Source: Translation for Translators)
