'Heavy' in the Bible

They went to the High Priests and Elders and said to them, "We have bound ourselves under a heavy curse to take no food till we have killed Paul.

"Sirs," he said, "I perceive that before long the voyage will be attended with danger and heavy loss, not only to the cargo and the ship but to our own lives also."

But coming to a place where two seas met, they stranded the ship, and her bow sticking fast remained immovable, while the stern began to go to pieces under the heavy hammering of the sea.
