30:29 You will sing
as you do in the evening when you are celebrating a festival.
You will be happy like one who plays a flute
as he goes to the mountain of the Lord, the Rock who shelters Israel.
42:10 Sing to the Lord a brand new song!
Praise him from the horizon of the earth,
you who go down to the sea, and everything that lives in it,
you coastlands and those who live there!
