'Enough' in the Bible

Would you keep yourselves till they were old enough? would you keep from having husbands for them? No, my daughters; but I am very sad for you that the hand of the Lord is against me.

And at meal-time Boaz said to her, Come here, and take some of the bread, and put your bit into the wine. And she took her seat among the grain-cutters: and he gave her dry grain, and she took it, and there was more than enough for her meal.

And she took it up and went into the town; and she let her mother-in-law see what she had got, and after taking enough for herself she gave her the rest.

And she took her rest at his feet till the morning: and she got up before it was light enough for one to see another. And he said, Let it not come to anyone's knowledge that the woman came to the grain-floor.
