Genesis 6:5; Genesis 6:9; Genesis 6:13

5 The LORD saw how great the wickedness of the human race had become on the earth, and that every inclination of the thoughts of the human heart was only evil all the time.
9 This is the account of Noah and his family. Noah was a righteous man, blameless among the people of his time, and he walked faithfully with God.
13 So God said to Noah, “I am going to put an end to all people, for the earth is filled with violence because of them. I am surely going to destroy both them and the earth.
