The same formula as verse 5 and 20 — families, tongues, lands, nations — closes Shem's section. Shem's line is the most important for the biblical narrative: it leads to Abraham, to Israel, and to Jesus.
Memory phrase: Through Shem's line, Jesus came to us.
Talk about it: How does knowing that Jesus traces back to Shem make the genealogy in Luke 3 come to life?
Prayer: God, thank You that You worked through Shem's family for thousands of years to bring Jesus to the world — and to me.
