"Now the Lord had said to Abram:
“Get out of your country,
From your family
And from your father’s house,
To a land that I will show you.
I will make you a great nation;
I will bless you
And make your name great;
And you shall be a blessing.
I will bless those who bless you,
And I will curse him who curses you;
And in you all the families of the earth shall be blessed.”"
