Genesis 18:32
30 Then Abraham said, “May the Lord not be angry so that I may speak! What if 30 are found there?” He replied, “I will not do it if I find 30 there.” 31 Abraham said, “Since I have undertaken to speak to the Lord, what if only 20 are found there?” He replied, “I will not destroy it for the sake of the 20.” 32 Finally Abraham said, “May the Lord not be angry so that I may speak just once more. What if 10 are found there?” He replied, “I will not destroy it for the sake of the 10.” 33 The Lord went on his way when he had finished speaking to Abraham. Then Abraham returned home.
Jeremiah 5:1
1 The Lord said, “Go up and down through the streets of Jerusalem. Look around and see for yourselves. Search through its public squares. See if any of you can find a single person who deals honestly and tries to be truthful. If you can, then I will not punish this city. 2 These people make promises in the name of the Lord. But the fact is, what they swear to is really a lie.” 3 Lord, I know you look for faithfulness. But even when you punish these people, they feel no remorse. Even when you nearly destroy them, they refuse to be corrected. They have become as hardheaded as a rock. They refuse to change their ways.
Notes and References
"... Yair Hoffman detects an echo here of Abraham’s dialogue with God in Genesis 18 over whether Sodom can be spared if ten just men can be found in it. That allusion mobilizes the trope of Israel as Sodom (compare Isaiah 1) and also makes the terms more generous: God would forgive Jerusalem if a single just man could be found there. ..."
