Genesis 18:29-31

Young's Literal Translation

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.'

³¹ And he saith, `Lo, I pray thee, I have willed to speak unto the Lord: peradventure there are found there twenty?' and He saith, `I do not destroy [it], because of the twenty.'
