to do to Sodom and Gomorrah, not, as Kurtz supposes, because Abraham had been constituted the hereditary possessor of the land, and Jehovah, being mindful of His covenant, would not do anything to it without his knowledge and assent (a thought quite foreign to the context), but because Jehovah had chosen him to be the father of the people of God, in order that, by instructing his descendants in the fear of God, he might lead them in the paths of righteousness, so that they might become partakers of the promised salvation, and not be overtaken by judgment. The destruction of Sodom and the surrounding cities was to be a permanent memorial of the punitive righteousness of God, and to keep the fate of the ungodly constantly before the mind of Israel. To this end Jehovah explained to Abraham the cause of their destruction in the clearest manner possible, that he might not only be convinced of the justice of the divine government, but might learn that when the measure of iniquity was full, no intercession could avert the judgment-a lesson and a warning to his descendants also. ==Verse 20== Gen 18:20 “The cry of Sodom and Gomorrah, yea it is great; and their sin, yea it is very grievous.” The cry is the appeal for vengeance or punishment, which ascends to heaven (Gen 4:10). The כּי serves to give emphasis to the assertion, and is placed in the middle of the sentence to give the greater prominence to the leading thought (cf. Ewald, §330).

After this explanation, the men (according to Gen 19:1, the two angels) turned from thence to go to Sodom (Gen 18:22); but Abraham continued standing before Jehovah, who had been talking with him, and approached Him with earnestness and boldness of faith to intercede for Sodom. He was urged to this, not by any special interest in Lot, for in that case he would have prayed for his deliverance; nor by the circumstance that, as he had just before felt himself called upon to become the protector, avenger, and deliverer of the land from its foes, so he now thought himself called upon to act as mediator, and to appeal from Jehovah’s judicial wrath to Jehovah’s
