And Boaz answered and said unto her, It hath fully been showed me, all that thou hast done unto thy mother-in-law since the death of thy husband; and how thou hast left thy father and thy mother, and the land of thy nativity, and art come unto a people that thou knewest not heretofore.

And she took it up, and went into the city; and her mother-in-law saw what she had gleaned: and she brought forth and gave to her that which she had left after she was sufficed.

And her mother-in-law said unto her, Where hast thou gleaned to-day? and where hast thou wrought? blessed be he that did take knowledge of thee. And she showed her mother-in-law with whom she had wrought, and said, The man's name with whom I wrought to-day is Boaz.

For the son dishonoreth the father, the daughter riseth up against her mother, the daughter-in-law against her mother-in-law; a man's enemies are the men of his own house.

For I came to set a man at variance against his father, and the daughter against her mother, and the daughter in law against her mother in law:

They shall be divided, father against son, and son against father; mother against daughter, and daughter against her mother; mother in law against her daughter in law, and daughter in law against her mother in law.
