'Trumpets' in the Bible

Then I saw the seven angels who are in the presence of God, and seven trumpets were given to them.

Then the seven angels who had the seven trumpets made preparations for blowing them.

Then I looked, and I heard a solitary eagle crying in a loud voice, as it flew across the sky, "Alas, alas, alas, for the inhabitants of the earth, because of the significance of the remaining trumpets which the three angels are about to blow!"
