And when Abram came out from the cave, he went to Noah and his son Shem, and he remained with them to learn the instruction of the Lord and his ways, and no man knew where Abram was, and Abram served Noah and Shem his son for a long time. And when Abram was in Noah's house thirty nine years, and Abram knew Yahweh from three years old. He went in the ways of Yahweh until he the day of his death as Noah and his son Shem had taught him.
