'Nothing' in the Bible

I went out full, and the Lord has sent me back again with nothing; why do you give me the name Naomi, seeing that the Lord has given witness against me, and the Ruler of all has sent sorrow on me?

And when she got ready to take up the grain, Boaz gave his young men orders, saying, Let her take it even from among the cut grain, and say nothing to her.

So Naomi said to her daughter-in-law Ruth, “My daughter, it is good for you to work with his female servants, so that nothing will happen to you in another field.”

And she said, He gave me these six measures of grain, saying, Do not go back to your mother-in-law with nothing in your hands.

Then she said, Do nothing now, my daughter, till you see what will come of this; for the man will take no rest till he has put this thing through.
