'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.

At mealtime Boaz said to her, “Come here, that you may eat of the bread and dip your piece of bread in the vinegar.” So she sat beside the reapers; and he served her roasted grain, and she ate and was satisfied and had some left.

They also gave me gall for my foodAnd 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.

Like one who takes off a garment on a cold day, or like vinegar on soda,Is he who sings songs to a troubled heart.
