Isaiah 50:7-8New Revised Standard Version (NRSV)
7 The Lord God helps me;
therefore I have not been disgraced;
therefore I have set my face like flint,
and I know that I shall not be put to shame;
8 he who vindicates me is near.
Who will contend with me?
Let us stand up together.
Who are my adversaries?
Let them confront me.
