Noah’s son in the ark
Shem first appears as one of Noah’s sons. Genesis names Shem, Ham, and Japheth before telling how God called Noah to build the ark in a violent and corrupt world (Genesis 5:32; Genesis 6:10). Scripture gives few personal details about Shem before the flood, but his place in Noah’s household matters.
When the flood came, Shem entered the ark with Noah, his brothers, their wives, and the animals God had brought to safety (Genesis 7:13). He was one of the eight people preserved through the flood. From Noah’s family, the biblical story describes the earth being repopulated (Genesis 9:18-19).
In the selfsame day entered Noah, and Shem, and Ham, and Japheth, the sons of Noah, and Noah's wife, and the three wives of his sons with them, into the ark;
Shem and Noah’s shame
After the flood, Noah became drunk and lay uncovered in his tent. Ham saw his father’s exposed state and told his brothers, while Shem and Japheth took a garment, walked backwards, and covered Noah without looking at him (Genesis 9:20-23). Their actions showed care for their father in an awkward, painful moment.
When Noah learned what had happened, he pronounced a curse on Canaan, Ham’s son, rather than on Ham or every one of Ham’s descendants (Genesis 9:24-25). This difficult passage must never be used to defend racism, slavery, or the mistreatment of any people. It does not give permission for that.
And Shem and Japheth took a garment, and laid it upon both their shoulders, and went backward, and covered the nakedness of their father; and their faces were backward, and they saw not their father's nakedness.
A blessing linked with the Lord
Noah’s response also included a blessing that named the Lord as Shem’s God (Genesis 9:26). This is one reason Shem’s descendants receive special attention as Genesis moves forward. The point is not that one ethnic group was inherently better than another. God chose a particular family line through which to carry forward his purposes of blessing.
Noah also spoke about Japheth dwelling in Shem’s tents (Genesis 9:27). Christians have understood that phrase in different ways, and the text does not explain every implication. Still, it points beyond the brothers’ immediate lives to a future shaped by God.
And he said, Blessed be the Lord God of Shem; and Canaan shall be his servant.
An ancestor of Abraham and Jesus
Shem’s family line is traced through his son Arphaxad. Genesis says Arphaxad was born two years after the flood, then continues the generations that eventually reach Terah, Abraham’s father (Genesis 11:10; Genesis 11:26). Through Abraham, God promised that all families of the earth would be blessed (Genesis 12:3).
Luke’s genealogy of Jesus includes Shem, using the name Sem in the KJV (Luke 3:36). So Shem is more than a name in an ancient family record. His life and descendants form one part of the long biblical story that leads towards God’s promise of blessing for the world.
