See if this helps, I copied it from Bible Gateway (great website for different translations of scripture). This is a summary of the 3 chapters;
Gen 13 - Abram is an exemplary man of faith. Being older than Lot, he by custom has first choice of the property, but he waives his right and grants Lot the first choice. Given their recent experiences in the famine, it is no wonder that Lot chooses the lush, fertile soils of the Jordan Valley for his new home. But as Lot moves his family east, he moves farther from Abram and closer to danger.
Gen 14 - This unusual encounter has sparked much interest over the centuries. Melchizedek, it seems, appears out of nowhere. There is no genealogical record for him; he is described simply as the priest-king of Salem, likely a reference to the city that will one day be known as Jerusalem. The Hebrew root of the name Salem means “peace” (
shalom). Melchizedek comes in peace, offering the victors a meal to sustain them on their journey home. Abram, in return, gives Melchizedek ten percent of the spoils claimed in battle. There are two other scriptural references to Melchizedek in
Psalm 110 and
Hebrews 7. The writer of Hebrews compares the priestly role of Jesus to the ancient priestly order of Melchizedek showing that Jesus’ role, like that of Melchizedek, is superior in every way to the later Levitical priests.
Gen 15 - This ritual may sound strange, but it is a common way of making agreements between parties in Abram’s day. The exact meaning is unclear, but the various elements and actions point to one undeniable fact: Abram and the Lord are entering into a relationship that has serious and long-lasting consequences. God’s covenant with Abram changes not only Abram’s future but the future of the world itself.
