Following are a number of back-translations as well as a sample translation for translators of Judges 20:23:

• Kupsabiny: “Those people of Israel went to Bethel and cried to God until evening. Those people asked God, ‘Are we again to go and fight our brothers of the clan of Benjamin?’ God at that time said to them, ‘Go and fight (them).’
  Then the people of Israel took courage and gathered at the place they had gathered the first day so as to fight the others.” (Source: Kupsabiny Back Translation)
• Newari: “Because the Israelites going up before the LORD wept until sundown, then they asked the LORD — "Should we go up again to fight with our brothers, the Benjaminites?"
  The LORD answered — "Attack them again."” (Source: Newari Back Translation)
• Hiligaynon: “The Israelinhon once-again went-up to Betel and wept there until evening. They asked the LORD, ‘Shall we fight again against our brothers Benjaminhon?’ The LORD replied, ‘Yes, you will-fight again.’ So they strengthened each other and they positioned again in the same place on the first day they attached.” (Source: Hiligaynon Back Translation)
• English: “Late that afternoon, the remaining Israeli men went to the place of worship and cried until the sun set. Then they asked Yahweh, ‘Should we attack the men of the tribe of Benjamin again, even though they are our fellow Israelis?’
  Yahweh replied, ‘Yes, attack them again.’ So the Israeli men encouraged each other.” (Source: Translation for Translators)
