'Delay' in the Bible

And now in loud voices they cried out, saying, "How long, O Sovereign Lord, the holy One and the true, dost Thou delay judgment and the taking of vengeance upon the inhabitants of the earth for our blood?"

"There shall be no further delay; but in the days when the seventh angel blows his trumpet--when he begins to do so--then the secret purposes of God are realized, in accordance with the good news which He gave to His servants the Prophets."
