'Heavy' in the Bible

So all the men of Judah and Benjamin gathered in Jerusalem within the three days. On the twentieth day of the ninth month, all the people sat in the square at the house of God, trembling because of this matter and because of the heavy rain.

But there are many people and it is the season of heavy rain; so we are unable to stand outside. Nor can the task be done in a day or two, for we have transgressed greatly in this matter.
