Job 38

 1Then the LORD answered Job out of the whirlwind, and said,

 2Who is this that darkeneth counsel by words without knowledge?

 3Gird up now thy loins like a man; for I will demand of thee, and answer thou me.

 4Where wast thou when I laid the foundations of the earth? declare, if thou hast understanding.

 5Who hath laid the measures thereof, if thou knowest? or who hath stretched the line upon it?

 6Whereupon are the foundations thereof fastened? or who laid the corner stone thereof;

 7When the morning stars sang together, and all the sons of God shouted for joy?

Who are the morning stars if not angels?  I believe angels sing but there is no salvation in it, so I won't demand anyone agree.
