• Hiligaynon: “Abraham again said, ‘Hopefully you will- not just -be-angry with me, Lord, for I will- still -ask. So/How-about, if perchance there are only 30 righteous people?’ The Lord answered, ‘I will- still not -destroy the city if I can-find 30 righteous-(ones).'” (Source: Hiligaynon Back Translation)
• English: “Abraham said, ‘God, please don’t be angry now. Let me speak again. What will you do if there are only 30 righteous people?’ He replied, ‘I will not do it if I find that there are 30 there.'” (Source: Translation for Translators)
