Midrash su Isaia 64:11

“For the conductor, a psalm of David, a song. Silence is praise to You, O God in Zion…” (Psalms 65:1-2) This is what Scripture says “I was silent from time immemorial; I am still, I restrain Myself. Like a travailing woman will I cry…” (Isaiah 42:14) And it says “Concerning these will You restrain Yourself, oh Lord…”(Isaiah 64:11) He said to them “I have no wrath…” the aspect of judgment dictates that I stay silent, “…would that I were thorns and brier in war!” (Isaiah 27:4) Thus said the Holy One: I am able to act, but the aspect of judgment constrains Me to silence. This is why it says ‘silence is praise to You’. You are able to hold silent and everyone praises You for being silent for that which was done to You in Zion and for the voice that was raised against Your Sanctuary, as it says “…they raised a clamor in the House of the Lord, as on a day of a festival.” (Lamentations 2:7) What voice did they raise? They said “Our hand was triumphant!” (Deuteronomy 32:27) and “Then He will say, "Where is their deity, the rock in which they trusted.” (Deuteronomy 32:37) This is ‘silence is praise to You’. You are silent and I am silent, as it says “Sit silent for the Lord and hope for Him…” (Psalms 37:7)
