Genesis 6 mentions that "there were giants in the earth" and includes a passage about "sons of God" taking "daughters of men" as wives, resulting in offspring described as "mighty men which were of old, men of renown."
As humanity multiplied on earth, their wickedness increased dramatically. Genesis 6 says that "every imagination of the thoughts of his heart was only evil continually," causing God deep grief over creating humankind. God resolved to wipe out all living creatures from the earth because of this widespread corruption and violence.
"But, Noah found grace in the eyes of the LORD" and is described as righteous and blameless among the people of his time. God instructed Noah to build an ark of cypress wood, providing specific dimensions. The ark was to have three decks and rooms throughout, and it was to be covered with pitch inside and out.
God announced His plan to bring a flood to destroy all life, but He established a covenant with Noah. God commanded Noah to bring his wife, sons, and his sons' wives into the ark, along with two (male and female) of every kind of animal to keep them alive. Noah was also instructed to store food for his family and the animals.
Genesis 6 concludes with Noah's obedience: "According to all that God commanded him, so did he."
