Isaiah 50

The Sovereign Lord has given me his words of wisdom,
so that I know how to comfort the weary.
Morning by morning he wakens me
and opens my understanding to his will.
The Sovereign Lord has spoken to me,
and I have listened.
I have not rebelled or turned away.
(verses 4-5)

Give us Thy words of wisdom that we know how to comfort the weary ... awaken us each morning and open our understanding to Thy will ... speak to us and have us listen ... O, that we do not rebel nor turn away!

Because the Sovereign Lord helps me,
I will not be disgraced.
Therefore, I have set my face like a stone,
determined to do his will.
And I know that I will not be put to shame.
(verse 7)

Because the Lord helps us, we will not be disgraced ... therefore, be determined to do His will ... knowing that we will not be put to shame.

If you are walking in darkness,
without a ray of light,

and rely on your God.
But watch out, you who live in your own light
and warm yourselves by your own fires.
This is the reward you will receive from me:
You will soon fall down in great torment.
(verses 10-11)

If walking in darkness ... either trust in the Lord and rely on God ... or live in own light and warm ourselves by own fires ...
