What role do genealogies play in understanding God's covenant promises?

Setting the scene in Nehemiah 7:34

“the men of Jericho, 345.” (Nehemiah 7:34)

• Nehemiah is rebuilding Jerusalem’s walls and community after exile.

• Chapter 7 counts those who returned; each family line is recorded.

• Verse 34, though brief, signals one brick in a larger genealogical structure—evidence that specific people, tied to specific places, really came home.

Why God preserves names

• Genealogies prove God’s promises are tethered to real history, not myth.

• They verify legal rights to land, Temple service, and inheritance (cf. Ezra 2:59–63).

• They answer the ache of exile—“Are we still God’s covenant people?”—with a resounding yes.

Genealogies and covenant identity

• Promise to Abraham: “In you all families of the earth will be blessed.” (Genesis 12:3)

– Lists show those families still exist and are being blessed.

• Promise at Sinai: “You will be My treasured possession.” (Exodus 19:5-6)

– Names demonstrate the treasured possession is intact.

• Promise to David: “I will establish your throne forever.” (2 Samuel 7:16)

– Preserved royal and priestly lines keep the messianic hope alive.

Promises traced from Abraham to the exiles

1. Abraham ➝ Isaac ➝ Jacob: covenant seed secured (Genesis 15:5; 26:3-4; 28:14).

2. Judah’s line ➝ David ➝ post-exilic Zerubbabel (1 Chronicles 3:19), noted again in Matthew 1:12.

3. Priestly line: Aaron ➝ Zadok ➝ sons of Zadok after exile (Ezra 2:36-39).

From exile lists to the Messiah

• Matthew 1 opens, “The record of the genealogy of Jesus Christ, the son of David, the son of Abraham.”

• Luke 3 traces Jesus “all the way to Adam” (Luke 3:38), showing the covenant’s global reach.

• The tiny entry “men of Jericho” helps bridge the gap between Old Testament promises and the New Testament fulfillment in Christ.

Personal takeaways today

• God knows and remembers individual names; He will not forget ours (Isaiah 49:15-16).

• His covenant plan moves through centuries undeterred; our moment in history matters inside that plan.

• As believers in Christ, we are “Abraham’s seed and heirs according to the promise” (Galatians 3:29), grafted into a genealogy of grace that cannot be broken.
