'Heavier' in the Bible

Let them put heavier labour on the men, that they may be taken up with it, and not regard vain words.

For now it would be heavier than the sand of the seas; therefore my words are vehement.

Even to-day is my complaint bitter: my stroke is heavier than my groaning.

A stone is heavy, and the sand weighty; but a fool's vexation is heavier than them both.
