'Heavy' in the Bible

saying, “Men, I sense [after careful thought and observation] that this voyage will certainly be a disaster and with great loss, not only of the cargo and the ship, but also of our lives.”

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.”’
