'Drop' in the Bible

Then she said, By the life of the Lord your God, I have nothing but a little meal in my store, and a drop of oil in the bottle; and now I am getting two sticks together so that I may go in and make it ready for me and my son, so that we may have a meal before our death.

For in the hand of the Lord is a cup, and the wine is red; it is well mixed, overflowing from his hand: he will make all the sinners of the earth take of it, even to the last drop.

See, the nations are to him like a drop hanging from a bucket, and like the small dust in the scales: he takes up the islands like small dust.
