Pieter Lastman, Abraham en de drie engelen, detail, ca. 1623, Hermitage Amsterdam 23 okt. 2017
Not long afterward, during the heat of the day, Abraham had been sitting at the entrance of his tent by the terebinths of Mamre. He looked up and saw three men in the presence of God. Then he ran and bowed to the ground to welcome them. Abraham then offered to wash their feet and fetch them a morsel of bread, to which they assented. Abraham rushed to Sarah’s tent to order cakes made from choice flour, then he ordered a servant-boy to prepare a choice calf. When all was prepared, he set curds, milk and the calf before them, waiting on them, under a tree, as they ate.[Genesis 18:1–8]
One of the visitors told Abraham that upon his return next year, Sarah would have a son. While at the tent entrance, Sarah overheard what was said and she laughed to herself about the prospect of having a child at their ages. The visitor inquired of Abraham why Sarah laughed at bearing a child at her age, as nothing is too hard for God. Frightened, Sarah denied laughing.
After eating, Abraham and the three visitors got up. They walked over to the peak that overlooked the ‘cities of the plain’ to discuss the fate of Sodom and Gomorrah for their detestable sins that were so great, it moved God to action. Because Abraham’s nephew was living in Sodom, God revealed plans to confirm and judge these cities. At this point, the two other visitors left for Sodom. Then Abraham turned to God and pleaded decrementally with Him (from fifty persons to less) that “if there were at least ten righteous men found in the city, would not God spare the city?” For the sake of ten righteous people, God declared that he would not destroy the city.[Genesis 18:17–33]
When the two visitors got to Sodom to conduct their report, they planned on staying in the city square. However, Abraham’s nephew, Lot, met with them and strongly insisted that these two “men” stay at his house for the night. A rally of men stood outside of Lot’s home and demanded that they bring out his guests so that they may “know” (v.5) them. However, Lot objected and offered his virgin daughters who had not “known” (v.8) man to the rally of men instead. They rejected that notion and sought to break down Lot’s door to get to his male guests,[Genesis 19:1–9] thus confirming the wickedness of the city and portending their imminent destruction.[Genesis 19:12–13]
Early the next morning, Abraham went to the place where he stood before God. He “looked out toward Sodom and Gomorrah” and saw what became of the cities of the plain, where not even “ten righteous” (v.18:32) had been found, as “the smoke of the land went up as the smoke of a furnace.”[Genesis 19:27–29]
