As a poor, foreign widow, Ruth was entitled to glean the fields. Evidently she knew the Israelite law handed down from Moses: “When you harvest your grain and forget a sheaf back in the field, don’t go back and get it; leave it for the foreigner, the orphan, and the widow so that GOD, your God, will bless you in all your work.” (The Message, Deuteronomy 24:19) So she went out to Boaz’s fields and worked behind his workers, picking up what they left behind. Boaz saw Ruth, and invited her to work in his fields throughout the harvest. In that way, Ruth’s safety was assured.
