29You will sing
as on the night of a holy festival,
and your heart will rejoice
like one who walks to the music of a flute,
going up to the mountain of the LORD,
to the Rock of Israel.
30And the LORD will cause His majestic voice to be heard
and His mighty arm to be revealed,
striking in angry wrath with a flame of consuming fire,
and with cloudburst, storm, and hailstones.
— Isaiah 30:29-30
