NHEB(i)
29 You will have a song, as in the night when a holy feast is kept; and gladness of heart, as when one goes with a flute to come to the LORD's mountain, to Israel's Rock.
30 The LORD will cause his glorious voice to be heard, and will show the descent of his arm, with the indignation of his anger, and the flame of a devouring fire, with a blast, storm, and hailstones.
