Boaz is introduced in the story as a kinsman of Elimelech, whose name means God-is-King. Boaz is depicted as a wealthy man from Bethlehem, which aligns him as a type of Christ. His name, meaning In-Him-is-Strength, further emphasizes his role as a strong and capable figure. Boaz first appears in the narrative when Ruth begins to glean in his field. His initial interaction with Ruth is marked by graciousness and provision. He instructs her to stay in his field, where she will be safe and provided for, symbolizing Christ's guidance and protection for Christians. Boaz's commands to Ruth are akin to Christ's instructions for spiritual sustenance and fellowship within the church. Boaz's generosity extends beyond mere permission to glean; he ensures Ruth has ample food, even allowing her to glean among the sheaves and instructing his workers to leave extra grain for her. This abundance reflects the overflowing grace and provision of Christ. As a righteous judge, Boaz demonstrates knowledge and discernment. He speaks to Ruth's heart, understanding her needs and character. His judgment is one of blessing and grace, rewarding Ruth for her sacrifices and loyalty. Boaz's judgment of Ruth's virtue parallels Christ's justification of believers. Boaz's role as a loving redeemer is evident in his determination to fulfill his promise to Ruth. He follows the law meticulously, ensuring the redemption process is fair and just. His relentless effort to redeem Ruth mirrors Christ's unwavering commitment to redeeming His people. The story concludes with Boaz marrying Ruth, and their son Obed, meaning Servant of God, symbolizes the fruit of Christ's work in believers—a new creation dedicated to serving and worshipping God.

Boaz, a man of stature and wealth in the community, woke suddenly at midnight, likely due to his feet being cold. He was surprised to find Ruth lying at his feet, which put him in a compromising situation. Despite the potentially scandalous nature of her actions, Boaz responded with maturity and praised Ruth for her kindness in choosing him over a younger man. He noted that everyone in Bethlehem held her in esteem for her virtue. Boaz is described as a man of great wealth, which likely implies more than just riches. In Ruth 4, Boaz is shown to be well-versed in conducting business and legal matters at the city gate, aligning with the description in Proverbs 31:23 of a husband known in the gates. Additionally, Boaz frequently called Ruth "my daughter" and was the first to describe her as a virtuous woman, which connects to Proverbs 31:28-29 where the husband praises his wife's excellence. Boaz also used the word "kindness" (hesed) when acknowledging Ruth's actions, highlighting a significant theme in the book of Ruth.

Boaz' actions toward Ruth provide insight into his character. He praises her kindness, which is the Hebrew word chesed, implying covenant loyalty. Ruth showed herself true to her adopted family and to Israel by choosing Boaz over a younger man. As a widow, she had to marry the near kinsman according to the covenant, and she obeyed it to the letter. Boaz reassures her, saying, "Do not fear," for he would do everything that she requested. He then makes another judgment, agreeing that she is virtuous. In the morning, he makes it his chief aim to make her his bride.
