what does the bible say?

Genealogies in the Bible serve multiple purposes. They confirm the historical reliability of events in the Bible, emphasize the importance of family, determine qualifications for specific roles, validate prophecies, and show how God has used a wide diversity of individuals throughout history. These genealogies are found in various books, including but not limited to Genesis, Numbers, Chronicles, Ezra, and the gospels of Matthew and Luke. They reveal important insights about the people and events in the Bible.

from the old testament

Genealogies in Genesis trace the lineage from Adam to Noah and then from Noah to Abraham, showing us the continuity of God's covenant with humanity (Genesis 5; 10; 11).
Genesis 4:17-24 reveals the lineage of Cain.
The records from Abraham to Isaac to Jacob, and then to the twelve tribes of Israel, show the fulfillment of God's promises and the formation of the nation of Israel (Genesis 21—35; 46).
Exodus 6 provides us with Moses’ genealogy.
In Numbers, genealogies help organize the tribes of Israel and determine their roles and inheritances as they journeyed through the wilderness (Numbers 1—4).
The books of Chronicles extensively list genealogies to establish the heritage and legitimacy of the Israelites, particularly focusing on the royal lineage of David (1 Chronicles 1—9).
The genealogy in Ezra emphasizes the importance of priestly and Levitical lines for those returning from the Babylonian exile to serve in the temple (Ezra 2).
Ruth 4 presents us with a genealogy from Perez to King David, including Obed, Ruth and Boaz’s son.

from the new testament

Matthew's genealogy of Jesus traces His lineage from Abraham through David. We see Jesus' fulfillment of Jewish prophecies and His rightful place in Jewish history (Matthew 1:1–17).
Luke's genealogy of Jesus traces His lineage back to Adam. This is Jesus' universal significance and connection to all humanity (Luke 3:23–38).
The inclusion of women in a genealogy broke cultural norms. That Matthew mentions Tamar, Rahab, Ruth, Bathsheba, and Mary shows us the important roles women played (Genesis 3:15). It also indicates Gentile inclusion in the lineage of Jesus, demonstrating that salvation is for all people. These women's stories also point to God's grace and His sovereignty (Matthew 1:3–6, 16).
Jesus' genealogies validate prophecies that the Messiah would come from the line of David and be a descendant of Abraham, which confirms the continuity and reliability of God's promises (Matthew 1:1; Luke 3:34).

implications for today

Genealogies in the Bible confirm the Bible's historical accuracy and remind us that God's plans span generations. They show that God uses all kinds of people to fulfill His purposes, regardless of their backgrounds. Through the inclusion of individuals like Rahab and Ruth in Jesus' lineage, we see that God values and uses everyone for His glory and His good purposes.

Genealogies offer assurance of God's reliable promises and meticulous plans. They connect us to a larger story of faith and show us our place in God's ongoing narrative. This understanding encourages us to live in a way that honors our spiritual heritage and contributes to the legacy we leave for future generations. Understanding this helps us reflect on the impact of faith on our families and communities.
