Parallel
Isaiah 30:29
Brenton's English Septuagint · Berean Standard Bible
Must ye always rejoice, and go into my holy places continually, as they that keep a feast? and must ye go with a pipe, as those that rejoice, into the mountain of the Lord, to the God of Israel?
You 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.
