1. Abram rescued Lot (1-17).
There were wars in Abram's time: 4 kings against 5. Kedoraomer and his 3 allies defeated 5 kings and captured everything in Sodom, Gomorrah and Lot too. Abram did not gloat over Lot who didn't care for Abram by choosing the better land when he left Abram. Abram rather had great compassion on Lot. He loved Lot and risked his life and all his possessions against the victorious kings of that ancient world. He boldly attacked the kings at night with only 318 trained men. He miraculously rescued Lot and brought a lot of spoils too.
2. I will accept nothing (18-24).
Melchizedek, a king of Salem, reminded Abram of God the Creator who gave him the victory. Abram acknowledged God by giving a tithe to Melchizedek. Then against the suggestion of the king of Sodom Abraham refused any of his material not even the thong of a sandal. Why? For he did not want the King of Sodom to say that he made Abram rich. Abram trusted in God who would make him rich and he only wanted to glorify God's name.
