And behold, Boaz came from Bethlehem. And he said to the reapers, “The LORD be with you!” And they answered, “The LORD bless you.” Then Boaz said to his young man who was in charge of the reapers, “Whose young woman is this?” And the servant who was in charge of the reapers answered, “She is the young Moabite woman, who came back with Naomi from the country of Moab. She said, ‘Please let me glean and gather among the sheaves after the reapers.’ So she came, and she has continued from early morning until now, except for a short rest.” Then Boaz said to Ruth, “Now, listen, my daughter, do not go to glean in another field or leave this one, but keep close to my young women. Let your eyes be on the field that they are reaping, and go after them. Have I not charged the young men not to touch you? And when you are thirsty, go to the vessels and drink what the young men have drawn.” Then she fell on her face, bowing to the ground, and said to him, “Why have I found favor in your eyes, that you should take notice of me, since I am a foreigner?” But Boaz answered her, “All that you have done for your mother-in-law since the death of your husband has been fully told to me, and how you left your father and mother and your native land and came to a people that you did not know before. The LORD repay you for what you have done, and a full reward be given you by the LORD, the God of Israel, under whose wings you have come to take refuge!” Then she said, “I have found favor in your eyes, my lord, for you have comforted me and spoken kindly to your servant, though I am not one of your servants.” And at mealtime Boaz said to her, “Come here and eat some bread and dip your morsel in the wine.” So she sat beside the reapers, and he passed to her roasted grain. And she ate until she was satisfied, and she had some left over. When she rose to glean, Boaz instructed his young men, saying, “Let her glean even among the sheaves, and do not reproach her. And also pull out some from the bundles for her and leave it for her to glean, and do not rebuke her.” (Ruth 2:4-16)
The pious and kind language between Boaz and his reapers shows that there were godly persons in Israel. Such language as this is seldom heard in our field; too often, on the contrary, what is immoral and corrupt. But true religion will teach a man to behave aright in all states and conditions; it will form kind masters and faithful servants, and cause harmony in families.
True religion will cause mutual love and kindness among persons of different ranks. It had these effects on Boaz and his men. When he came to them he prayed for them. They did not, as soon as he was out of hearing curse him, as some ill-natured servants that hate their master's eye, but they returned his courtesy. Things are likely to go on well where there is such good-will as this between masters and servants. They expressed their kindness to each other by praying one for another.
Boaz inquired concerning the stranger he saw, and ordered her to be well treated. Masters must take care, not only that they do not hurt themselves, but that they suffer not their servants and those under them to do wrong.
Ruth humbly owned herself unworthy of favors, seeing she was born and brought up a heathen. It well becomes us all to think humbly of ourselves, esteeming others better than ourselves. And let us, in the kindness of Boaz to Ruth, note the kindness of the Lord Jesus Christ to poor sinners.
