So she gleaned in the field until evening. Then she beat out what she had gleaned, and it was about an ephah of barley. And she took it up and went into the city. Her mother-in-law saw what she had gleaned. She also brought out and gave her what food she had left over after being satisfied. And 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 man's name with whom I worked today is Boaz.” And Naomi said to her daughter-in-law, “May he be blessed by the LORD, whose kindness has not forsaken the living or the dead!” Naomi also said to her, “The man is a close relative of ours, one of our redeemers.” And Ruth the Moabite said, “Besides, he said to me, ‘You shall keep close by my young men until they have finished all my harvest.’” And Naomi said to Ruth, her daughter-in-law, “It is good, my daughter, that you go out with his young women, lest in another field you be assaulted.” So she kept 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. (Ruth 2:17-23)
Parents should examine their children, as Naomi did, not to frighten or discourage them, so as to make them hate home, or tempt them to tell a lie; but to commend them if they have done well, and with mildness to reprove and caution them if they have done otherwise.
It is a good question for us to ask ourselves every night, where have I gleaned to-day? What improvement have I made in knowledge and grace? What have I done that will turn to a good account? When the Lord deals bountifully with us, let us not be found in any other field, nor seeking for happiness and satisfaction in the creature. We lose Divine favors, if we slight them.
Ruth dutifully observed her mother's directions. And when the harvest was ended, she kept her aged mother company at home. Dinah went out to see the daughters of the land; her vanity ended in disgrace, 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.
