Ruth 2:21-23

And Ruth the Moabitess said, He said unto me also, Thou shalt keep fast by my young men, until they have ended all my harvest. And Naomi said unto Ruth her daughter in law, It is good, my daughter, that thou go out with his maidens, that they meet thee not in any other field. So she kept fast by the maidens of Boaz to glean unto the end of barley harvest and of wheat harvest; and dwelt with her mother in law.
