Isaiah 50-52 - Sustain With a Word

From today's Bible reading:

Isaiah 50:

Thus says the LORD:

Where is your mother's certificate of divorce, with which I sent her away?
Or which of my creditors is it to whom I have sold you?

Behold, for your iniquities you were sold,
and for your transgressions your mother was sent away.

Why, when I came, was there no man;
why, when I called, was there no one to answer?

Is my hand shortened, that it cannot redeem?
Or have I no power to deliver?

The Lord GOD has given me
the tongue of those who are taught,
that I may know how to sustain with a word
him who is weary.

Isaiah 51:

Listen to me, you who pursue righteousness,
you who seek the LORD:
look to the rock from which you were hewn,
and to the quarry from which you were dug.

Give attention to me, my people,
and give ear to me, my nation;
for a law will go out from me,
and I will set my justice for a light to the peoples.

Lift up your eyes to the heavens,
and look at the earth beneath;
for the heavens vanish like smoke,
the earth will wear out like a garment,
and they who dwell in it will die in like manner;
but my salvation will be forever,
and my righteousness will never be dismayed.

And the ransomed of the LORD shall return
and come to Zion with singing;
everlasting joy shall be upon their heads;
they shall obtain gladness and joy,
and sorrow and sighing shall flee away.

And where is the wrath of the oppressor?

He who is bowed down shall speedily be released;
he shall not die and go down to the pit,
neither shall his bread be lacking.

Isaiah 52:

Awake, awake,
put on your strength, O Zion;
put on your beautiful garments,
O Jerusalem, the holy city;
for there shall no more come into you
the uncircumcised and the unclean.
Shake yourself from the dust and arise;
be seated, O Jerusalem;
loose the bonds from your neck,
O captive daughter of Zion.

For thus says the LORD:

You were sold for nothing, and you shall be redeemed without money.

How beautiful upon the mountains
are the feet of him who brings good news,
who publishes peace, who brings good news of happiness,
who publishes salvation,
who says to Zion, Your God reigns.

The voice of your watchmen—they lift up their voice;
together they sing for joy;
for eye to eye they see
the return of the LORD to Zion.

Break forth together into singing,
you waste places of Jerusalem,
for the LORD has comforted his people;
he has redeemed Jerusalem.

The LORD has bared his holy arm
before the eyes of all the nations,
and all the ends of the earth shall see
the salvation of our God.

As many were astonished at you—his appearance was so marred, beyond human semblance, and his form beyond that of the children of mankind—so shall he sprinkle many nations; kings shall shut their mouths because of him; for that which has not been told them they see, and that which they have not heard they understand.
