Ye shall have a song, as in the night [when] a holy solemnity is kept; and gladness of heart, as when one goeth with a pipe to come into the mountain of the LORD, to the mighty One of Israel.
Berean Study Bible (BSB) - Isaiah 30:29 >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.
