KJV
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.
BSB
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.
