Isaiah 51:1-2

The Voice

51 Listen closely, you who diligently work for justice
    and look for the Eternal One, for what is fair and true.
It would be good for you to look back, look to the place from where you came,
    the rock out of which you were shaped and the quarry from where you were mined.
² Look to your spiritual ancestors—
    Abraham, your father, and Sarah, who birthed you.
Abraham was only one person when I called him.
    But with generous goodness, I made from him a numerous people.
