'Something' in the Bible

and in front of the throne was something like a sea of glass, like crystal. In the middle of the throne and around the throne were four living creatures full of eyes in front and in back.

Then I heard something like a voice from among the four living creatures saying, "A quart of wheat will cost a day's pay and three quarts of barley will cost a day's pay. But do not damage the olive oil and the wine!"

Then the second angel blew his trumpet, and something like a great mountain of burning fire was thrown into the sea. A third of the sea became blood,

Now the locusts looked like horses equipped for battle. On their heads were something like crowns similar to gold, and their faces looked like men's faces.

Then I saw something like a sea of glass mixed with fire, and those who had conquered the beast and his image and the number of his name. They were standing by the sea of glass, holding harps given to them by God.
