'Heavy' in the Bible

Like a club and a sword and a piercing arrowIs a man who testifies falsely against his neighbor (acquaintance).

Like one who takes off a garment in cold weather, or like [a reactive, useless mixture of] vinegar on soda,Is he who [thoughtlessly] sings [joyful] songs to a heavy heart.

Stone is heavy and the sand weighty,But a fool’s [unreasonable] wrath is heavier and more burdensome than both of them.
