'Vinegar' in the Bible

he shall abstain from wine and strong drink; he shall drink no vinegar, whether made from wine or strong drink, nor shall he drink any grape juice nor eat fresh or dried grapes.

They (self-righteous hypocrites) also gave me gall [poisonous and bitter] for my food,And for my thirst they gave me vinegar to drink.

Like vinegar to the teeth and smoke to the eyes,So is the lazy one to those who send him to work.

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.
