'Midst' in the Bible

And I heard what seemed to be a voice speaking in the midst of the four living creatures, and saying, "A quart of wheat for a shilling, and three quarts of barley for a shilling; but do not injure either the oil or the wine."

And from the midst of the smoke there came locusts on to the earth, and power was given to them resembling the power which earthly scorpions possess.
