Background and Context:
The account of Ruth gleaning in Boaz's field is found in the Book of Ruth, specifically in Ruth 2. This narrative is set during the time of the judges, a period characterized by social and religious upheaval in Israel. The account of Ruth, a Moabite woman, unfolds against this backdrop, highlighting themes of loyalty, providence, and redemption.

Ruth's Journey and Decision:
Ruth, a Moabite widow, chooses to accompany her mother-in-law, Naomi, back to Bethlehem after the death of her husband, Mahlon. Despite Naomi's urging to return to her own people, Ruth's famous declaration of loyalty is recorded in Ruth 1:16-17 : "Do not urge me to leave you or to turn from following you. For wherever you go, I will go, and wherever you live, I will live. Your people will be my people, and your God will be my God. Where you die, I will die, and there I will be buried. May the LORD punish me, and ever so severely, if anything but death separates you and me."

Gleaning in the Field:
Upon arriving in Bethlehem, Ruth seeks to provide for herself and Naomi by gleaning in the fields during the barley harvest. The practice of gleaning was a provision in the Mosaic Law that allowed the poor and foreigners to gather leftover crops from the fields (Leviticus 19:9-10, Deuteronomy 24:19). Ruth's choice to glean demonstrates her industriousness and humility.

Boaz's Field:
Ruth "happens" to glean in the field of Boaz, a wealthy and influential relative of Naomi's late husband, Elimelech. This "chance" encounter is seen as a divine orchestration, showcasing God's providential care. Boaz, upon noticing Ruth, inquires about her and learns of her loyalty to Naomi. He extends kindness and protection to her, instructing his workers to allow her to glean among the sheaves and to leave extra grain for her (Ruth 2:8-9, 15-16).

Boaz's Kindness and Protection:
Boaz's actions reflect the character of a godly man who adheres to the spirit of the Law, going beyond mere obligation. He acknowledges Ruth's faithfulness and prays for her reward from the LORD, under whose wings she has sought refuge (Ruth 2:12). Boaz's generosity and protection foreshadow his role as a kinsman-redeemer, a central theme in the narrative.

Significance in the Lineage of David:
Ruth's gleaning in Boaz's field sets the stage for her eventual marriage to Boaz, which leads to the birth of Obed, the grandfather of King David. This union is significant in the biblical narrative, as it integrates a Moabite woman into the lineage of David and, ultimately, Jesus Christ, highlighting the inclusivity of God's redemptive plan.

Theological Implications:
Ruth's account, particularly her gleaning in Boaz's field, illustrates the themes of divine providence, redemption, and the breaking down of ethnic barriers. It underscores the importance of faithfulness, kindness, and the fulfillment of God's law through love and compassion. The narrative serves as a testament to God's care for the marginalized and His ability to bring about His purposes through ordinary events and people.
