Ruth supported herself and her mother-in-law sparsely with the ears of grain which she gathered in the fields. Association with so pious a woman as Naomi had already exercised great influence upon her life and ways. Boaz was astonished to notice that if the reapers let more than two ears fall, in spite of her need she did not pick them up, for the gleaning assigned to the poor by law does not refer to quantities of more than two ears inadvertently dropped at one time.
Boaz also admired her grace, her decorous conduct, her modest demeanor. When he learned who she was, he commended her for her attachment to Judaism. To his praise she returned: "Thy ancestors found no delight even in Timna, the daughter of a royal house. As for me, I am a member of a low people, abominated by thy God, and excluded from the assembly of Israel."
For the moment Boaz failed to recollect the Halakah bearing on the Moabites and Ammonites. A voice from heaven reminded him that only their males were affected by the command of exclusion. This he told to Ruth, and he also told her of a vision he had had concerning her descendants. For the sake of the good she had done to her mother-in-law, kings and prophets would spring from her womb.
