But there was one man who God believed to be worthy of saving: Noah. As Genesis says, “Noah was a just man and perfect in his generations, and Noah walked with God.” God also decides to save Noah’s wife and his sons, Shem, Ham, and Japheth, along with their wives.
God’s punishment of humanity, excepting Noah and his kin, is to take the form of a huge flood. He warns Noah of his intention and bids him to build an ark, giving him detailed instructions, “The length of the ark shall be three hundred cubits, the breadth of it fifty cubits, and the height of it thirty cubits.”
God further instructs Noah that he should embark not only himself and his family, but also examples of all the animals of the world. He tells Noah, “And of every living thing of all flesh, two of every sort shalt thou bring into the ark, to keep them alive with thee; they shall be male and female.”
