And Ruth the Moabitess said, He said unto me also, Thou shalt keep fast by my young men, until they have ended all my harvest.

Wesley's Notes

2:21 Harvest - Both barley - harvest, and wheat - harvest. She tells what kindness Boaz had shewed her; but not, how he had commended her. Humility teaches not only not to praise ourselves, but not to be forward in repeating the praise which others have given us.

Jamieson-Fausset-Brown Bible Commentary

21. all my harvest-both barley and wheat harvests. The latter was at the end of May or the beginning of June.

Matthew Henry's Concise Commentary

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, 2Jo 1:8. 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 favours, 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, Ge 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.
