ISA 30:29

29 But [his people] will sing joyfully like they sing during the nights when they celebrate a holy festival. They will be very joyful, like [SIM] [a large group of his people] are joyful when they go up to Zion Hill in Jerusalem, along with men playing flutes [when they are all going there to worship Yahweh]. He is [like] [MET] a huge rock under which [we] Israeli people [are safe].
