4The Sovereign Lord has taught me what to say,
so that I can strengthen the weary.
Every morning he makes me eager
to hear what he is going to teach me.
5The Lord has given me understanding,
and I have not rebelled
or turned away from him.
6I bared my back to those who beat me.
I did not stop them when they insulted me,
when they pulled out the hairs of my beard
and spat in my face.
7But their insults cannot hurt me
because the Sovereign Lord gives me help.
I brace myself to endure them.
I know that I will not be disgraced,
8for God is near,
and he will prove me innocent.
Does anyone dare to bring charges against me?
Let us go to court together!
Let him bring his accusation!
9The Sovereign Lord himself defends me—
who, then, can prove me guilty?
All my accusers will disappear;
they will vanish like moth-eaten cloth.
Isaiah has the difficult task of saying difficult things to powerful people. And for speaking these truths he will suffer. We're not very good at speaking up for what is right - we fear the consequence. Isaiah invites his detractors to take him to court. Although Jesus' trial is a sham - ultimately - God is his judge. He is vindicated.
Lord, teach me what to say, to strengthen the weary - to gain understanding.
