Genesis 12:1-3
12:1 The LORD had said to Abram , "Leave your country, your people and your father's household and go to the land I will show you. 

2 "I will make you into a great nation 
and I will bless you;
I will make your name great,
and you will be a blessing. 
3 I will bless those who bless you,
and whoever curses you I will curse;
and all peoples on earth 
will be blessed through you."
