'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.

and told them, “Men, I can see that this voyage is headed toward damage and heavy loss, not only of the cargo and the ship but also of our lives.”

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.

and [he commanded] the rest to follow, some on [floating] planks, and others on various things from the ship. And so it was that all of them were brought safely to land.

“For the heart (the understanding, the soul) of this people has become dull (calloused),And with their ears they scarcely hear,And they have shut their eyes [to the truth];Otherwise they might see with their eyes,And hear with their ears,And understand with their heart and return [to Me],And I would heal them.”’
