'Mass' in the Bible

The locusts came up over all the land of Egypt and settled down in the whole territory, a very dreadful mass of them; never before were there such locusts as these, nor will there ever be again.

When the dust hardens into a massAnd the clods stick together [because of the heat]?

Therefore thus says the Lord God, “Behold, I will give the land of Egypt to Nebuchadnezzar king of Babylon. And he will carry off her wealth and capture her spoil and seize her plunder; and it shall be the wages for his army.

“A sword will come upon Egypt,And anguish and trembling will be in Ethiopia (Cush),When the slain fall in EgyptAnd they [of Babylon] carry away her great mass of people and her richesAnd her foundations are torn down.

“But I will remove the northern army far away from you,And I will drive it into a parched and desolate land,With its forward guard into the eastern sea (Dead Sea)And with its rear guard into the western sea (Mediterranean Sea).And its stench will arise and its foul odor of decay will come up [this is the fate of the northern army in the final day of the Lord],For He has done great things.”
