After a somewhat humiliating encounter in Egypt, Abram returns to the promise land and makes his way back to Bethel, which means the "House of God". It's important for us when we fail to come back to the place of the altar, and get back to walking with God. Abram and Lot part ways due to strife between their herdsmen, and Abram is willing to yield and gives preference to Lot. Lot then being governed by the lust of his eyes, chooses for himself to pitch his tent even as far as Sodom. We will see him become more and more settled in his compromise, as he will be dwelling in Sodom (Gen 14:12), and then sitting in the gates of, and having a house in Sodom (Gen 19:1-2).
In Chapter 14 we are given account of a war that takes place between Kings of the East, and the Kings in the region of Sodom and Gomorrah. We will see Lot then taken captive in this battle. Compromise may seem minor when it begins, but it leads to captivity. Abram goes and lays his own neck on the line to deliver his brother's son Lot, as well as the people of Sodom and Gomorrah. He then has 2 very interesting encounters, one with Melchizedek the King of Salem (the King of Righteousness and the King of Peace), and one with the King of Sodom, whose name means "son of evil".
