17 So she gleaned in the field until evening. Then she beat out what she had gleaned, and it was about an ephah of barley. 18 She picked it up and came into the town, and her mother-in-law saw how much she had gleaned. Then she took out and gave her what was left over after she herself had been satisfied. 19 Her mother-in-law said to her, "Where did you glean today? And where have you worked? Blessed be the man who took notice of you." So she told her mother-in-law with whom she had worked, and said, "The name of the man with whom I worked today is Boaz." 20 Then Naomi said to her daughter-in-law, "Blessed be he by the Lord, whose kindness has not forsaken the living or the dead!" Naomi also said to her, "The man is a relative of ours, one of our nearest kin." 21 Then Ruth the Moabite said, "He even said to me, "Stay close by my servants, until they have finished all my harvest.' " 22 Naomi said to Ruth, her daughter-in-law, "It is better, my daughter, that you go out with his young women, otherwise you might be bothered in another field." 23 So she stayed close to the young women of Boaz, gleaning until the end of the barley and wheat harvests; and she lived with her mother-in-law.

Commentary on Ruth 2:17-23

(Read Ruth 2:17-23)

It encourages industry, that in all labour, even that of gleaning, there is profit. Ruth was pleased with what she gained by her own industry, and was careful to secure it. Let us thus take care that we lose not those things which we have wrought, which we have gained for our souls' good, Genesis 34. Ruth kept at home, and helped to maintain her mother, and went out on no other errand than to get provision for her; her humility and industry ended in preferment.
