2 Corinthians 6:14 (NAS)

Do not be bound together with unbelievers; for what partnership have righteousness and lawlessness, or what fellowship has light with darkness?

Genesis 1:28 (NAS) 

God blessed them; and God said to them,“Be fruitful and multiply, and fill the earth, and subdue it; and rule over the fish of the sea and over the birds of the sky and over every living thing that moves on the earth."
