26 And Jehovah said, If I find at Sodom fifty righteous within the city, then I will forgive all the place for their sakes. 27 And Abraham answered and said, Behold now, I have ventured to speak unto the Lord; I, who am dust and ashes. 28 Perhaps there may want five of the fifty righteous: wilt thou destroy all the city on account of the five? And he said, If I shall find forty-five there, I will not destroy [it]. 29 And he continued yet to speak with him, and said, Perhaps there may be forty found there. And he said, I will not do it for the forty's sake. 30 And he said, Oh, let not the Lord be angry that I speak! Perhaps there may be thirty found there. And he said, I will not do it if I find thirty there. 31 And he said, Behold now, I have ventured to speak with the Lord. Perhaps there may be twenty found there. And he said, I will not destroy [it] for the twenty's sake. 32 And he said, Oh, let not the Lord be angry, that I speak yet but this time! Perhaps there may be ten found there. And he said, I will not destroy [it] for the ten's sake. 33 And Jehovah went away when he had ended speaking to Abraham; and Abraham returned to his place.

Commentary on Genesis 18:23-33
(Read Genesis 18:23-33)
Here is the first solemn prayer upon record in the Bible; and it is a prayer for the sparing of Sodom. Abraham prayed earnestly that Sodom might be spared, if but a few righteous persons should be found in it. Come and learn from Abraham what compassion we should feel for sinners, and how earnestly we should pray for them. We see here that the effectual, fervent prayer of a righteous man avails much. Abraham, indeed, failed in his request for the whole place, but Lot was miraculously delivered. Be encouraged then to expect, by earnest prayer, the blessing of God upon your families, your friends, your neighbourhood. To this end you must not only pray, but you must live like Abraham. He knew the Judge of all the earth would do right. He does not plead that the wicked may be spared for their own sake, or because it would be severe to destroy them, but for the sake of the righteous who might be found among them. And righteousness only can be made a plea before God. How then did Christ make intercession for transgressors? Not by blaming the Divine law, nor by alleging aught in extenuation or excuse of human guilt; but by pleading HIS OWN obedience unto death.
