Isaiah continues to describe some future Day of judgment and restoration.
Isaiah 64:1-3, Please come down!
Oh, that you would rend the heavens and come down,
that the mountains would tremble before you!
As when fire sets twigs ablaze
and causes water to boil,
come down to make your name known to your enemies
and cause the nations to quake before you!
For when you did awesome things that we did not expect,
you came down, and the mountains trembled before you.
Isaiah begs for YHWH to show Himself. His appearance would disrupt the nations, just like a fire causes water to boil. This poem has an envelope structure, beginning with an appeal to "rend the heavens and come down" and ending with "came down and the mountains trembled."
Isaiah 64:4-5, How can we be saved?
Since ancient times no one has heard,
no ear has perceived,
no eye has seen any God besides you,
who acts on behalf of those who wait for him.
You come to the help of those who gladly do right,
who remember your ways.
But when we continued to sin against them,
you were angry.
How then can we be saved?
In this short praise piece, Isaiah acknowledges that there is no one but God and then confesses that the people of Israel do not deserve salvation.
Isaiah 64:6-7, All unclean
All of us have become like one who is unclean,
and all our righteous acts are like filthy rags;
we all shrivel up like a leaf,
and like the wind our sins sweep us away.
No one calls on your name
or strives to lay hold of you;
for you have hidden your face from us
and have given us over to our sins.
"All our righteousness like filthy rags", says Isaiah. None of us, he continues, seek YHWH or calls on Him, and yes, He hides His face. The term "filthy rags" represents the bloody cloths from a woman's menstrual period.
Grogan (p. 343) writes "Verses 5-7 present a many-sided doctrine of sin, remarkably full for an OT passage."
Isaiah 64:8-9, Clay and potter
Yet you, LORD, are our Father.
We are the clay, you are the potter;
we are all the work of your hand.
Do not be angry beyond measure, LORD;
do not remember our sins forever.
Oh, look on us, we pray,
for we are all your people.
In this metaphor, the clay challenges the potter -- why have you made me so? This is like those who ask the same of YHWH. Jeremiah gives a clear parable in Jeremiah 18:1-6 of God being the potter working with clay. This becomes a favorite metaphor for the prophets, showing up here and in Isaiah 29:16 and Isaiah 45:9. In the New Testament, Paul quotes this passage in Romans 9:19-21.
Isaiah 64:10-12, Destroyed
Your sacred cities have become a wasteland;
even Zion is a wasteland, Jerusalem a desolation.
Our holy and glorious temple, where our ancestors praised you,
has been burned with fire,
and all that we treasured lies in ruins.
After all this, LORD, will you hold yourself back?
Will you keep silent and punish us beyond measure?
In Isaiah 63:15, God's throne is called qāḏ·šə·ḵā wə·ṯip̄·’ar·te·ḵā, translated "(your) holy and glorious" throne. In verse 11 here, that phrase is repeated. The temple in Jerusalem is described as "(our) holy and glorious" (qā·ḏə·šê·nū wə·ṯip̄·’ar·tê·nū) temple. The temple in Jerusalem is a "shadow" of the throne of YHWH in heaven. (This is made explicit in the New Testament, in Hebrews 8:1-6, where the Messiah serves as high priest in that heavenly temple.)
The city of Jerusalem and its beautiful temple have been laid waste and are destroyed. The chapter ends with a cry for YHWH to respond to the ruins and to not be silent. The next two chapters bring the answer to this prayer.
