'Vinegar' in the Bible

from wine and strong drink he doth keep separate; vinegar of wine, and vinegar of strong drink he doth not drink, and any juice of grapes he doth not drink, and grapes moist or dry he doth not eat;

And Boaz saith to her, 'At meal-time come nigh hither, and thou hast eaten of the bread, and dipped thy morsel in the vinegar.' And she sitteth at the side of the reapers, and he reacheth to her roasted corn, and she eateth, and is satisfied, and leaveth.

And they give for my food gall, And for my thirst cause me to drink vinegar.

As vinegar to the teeth, And as smoke to the eyes, So is the slothful to those sending him.

Whoso is taking away a garment in a cold day, Is as vinegar on nitre, And a singer of songs on a sad heart.
