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.
Jewish Publication Society of America Version (JPS1917) - Isaiah 30:29 >Ye shall have a song as in the night when a feast is hallowed; and gladness of heart, as when one goeth with the pipe to come into the mountain of the LORD, to the Rock of Israel.
