Isaías 30:29

29 And you will sing as on the night you celebrate a holy festival; your hearts will rejoice as when people playing pipes go up to the mountain of the Lord, to the Rock of Israel.

29 Ye shall have a song as in the night when a holy feast is kept; and gladness of heart, as when one goeth with a pipe to come unto the mountain of Jehovah, to the Rock of Israel.
