Genesis 18:26
“And the Lord said, If I find in Sodom fifty righteous within the city, then I will spare all the place for their sakes.”
KJV
Read in Genesis 18Meaning
The LORD answers that if fifty righteous people are found in Sodom, he will spare the whole place for their sake.

Reflection
The response makes space for mercy within the discussion of judgment and encourages Abraham to continue his intercession.
