Isaiah 5:12

5:12 They have stringed instruments, tambourines, flutes,

and wine at their parties.

So they do not recognize what the Lord is doing,

they do not perceive what he is bringing about.

Isaiah 30:29

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.
