“You shall have a song

As in the night

When a holy feast is kept.

You shall have

Gladness of heart,

As when one sets out

To the sound of the flute

To go to the mountain of Yahweh,

To the Rock of Israel.”

The Israelites were to be as happy as when they have a song at night during their holy feasts. They would have a glad heart. The sound of the flute could be heard. They were about to go up to the mountain of Yahweh, probably in Jerusalem. This was the rock of Israel, Yahweh.
