What does Genesis 6:21 mean?
God's last instruction to Noah in this extended passage has to do with the practical matter of food. In addition to building the ark and planning for all the animals that will come to the ark to be saved, Noah must consider what food will be necessary for the journey. He and his family will need to acquire and store every kind of food that the animals, birds, and insects will need to eat, and they will need to stockpile enough of it to last for the duration of the trip.As with other parts of the story, specific details are not given. We don't know what specific kinds of foods were to be brought. All we know is that God's covenant promise to save Noah and his family would require Noah to accept certain responsibilities. Among these are the need to build, plan, store, schedule, and do all the work necessary to be prepared when the floodwaters came.
Genesis 6:9-22 begins another new section in Genesis called the ''generations of Noah.'' Because of humanity's power and wickedness, the earth had become filled with violence and sinfulness. By contrast, Noah was a righteous, blameless man who walked with God. God chooses to declare to Noah His plan to end all land-dwelling life on earth, but also to save Noah and his family and two of every animal. Noah obeys God's command to build the ark that would preserve the human race from total destruction in the flood.
God sees. In the first chapter of Genesis, God saw that all He had made was good. Now, many generations after sin entered the world, God sees that all man has made is wickedness and evil. Human beings have used their power for violence and destruction. God declares His plan to wipe out all land-dwelling life on the face of the earth. He will however, preserve humanity and animal life for a new beginning through the one righteous man, Noah, and a huge life-giving structure called an ark.
