Kosam is a person mentioned in the genealogy of Jesus in the Gospel of Luke, chapter 3. He was the son of Elmadan and the father of Addi. Although there is no detailed story about him in the Bible, he plays a role in the lineage that connects Jesus to David and further back to Adam.
Kosam is listed as one of Jesus' ancestors in the genealogical record that Luke wrote down. He is placed between Elmadan and Addi in the lineage from Jesus back to God through the line of David and Nathan.
Kosam belongs to that branch of David's descendants that goes through Nathan, as opposed to Matthew's genealogy which follows the line of Solomon. This emphasizes that Jesus descended from David through multiple lines.
As a link in the lineage from David to Jesus, Kosam testifies to God's faithfulness in fulfilling the promise of a Messiah from David's house, even through unknown and humble generations.
God's Promise to David Fulfilled Through Generations
Through people like Kosam, God's covenant with David regarding an eternal throne was passed down from generation to generation, all the way to Jesus Christ.
12When your days are done and you rest with your fathers, I will raise up your offspring after you, who will come from your own body, and I will establish his kingdom.
