Genesis 18:28 YLT

²⁶  And Jehovah saith, 'If I find in Sodom fifty righteous in the midst of the city, then have I borne with all the place for their sake.'

²⁷  And Abraham answereth and saith, 'Lo, I pray thee, I have willed to speak unto the Lord, and I -- dust and ashes;

²⁸  peradventure there are lacking five of the fifty righteous -- dost Thou destroy for five the whole of the city?' and He saith, 'I destroy 'it' not, if I find there forty and five.'

²⁹  And he addeth again to speak unto Him and saith, 'Peradventure there are found there forty?' and He saith, 'I do 'it' not, because of the forty.'

³⁰  And he saith, 'Let it not be, I Pray thee, displeasing to the Lord, and I speak: peradventure there are found there thirty?' and He saith, 'I do 'it' not, if I find there thirty.'
