19 "Where did you gather all this grain today?" Naomi asked. "Where did you work? May the Lord bless the one who helped you!" So Ruth told her mother-in-law about the man in whose field she had worked. She said, "The man I worked with today is named Boaz."

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.
