Genesis 12:2-4

And I will make of you a great nation, and I will bless you and make your name great, so that you will be a blessing. I will bless those who bless you, and him who dishonors you I will curse, and in you all the families of the earth shall be blessed.” So Abram went, as the LORD had told him, and Lot went with him. Abram was seventy-five years old when he departed from Haran.
