Genesis 12:2-4

I will make you a great nation, and I will bless you. I will make you famous, and you will be a blessing to others. I will bless those who bless you, and I will place a curse on those who harm you. And all the people on earth will be blessed through you.” So Abram left Haran as the LORD had told him, and Lot went with him. At this time Abram was 75 years old.
