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 serves as a type of Christ, and his actions toward Ruth reveal the Savior's character, especially in His office of Judge, since judgment begins at the house of God (I Peter 4:17). After giving Ruth five instructions, Boaz praises her chesed, her covenant loyalty, shown in remaining true to her adopted family and to Israel. She chose him over a younger man and obeyed the covenant's requirement that a widow marry the near kinsman. Spiritually, she acted contrary to the course of this world, doing what was right rather than following carnal desires. Boaz reassures her not to fear and promises to do all she requests, paralleling Christ's words in Luke 12:32 and John 14:13-14. He also judges her virtuous, which typifies Christ pronouncing the believer righteous through redemption and justification by His blood. Boaz then makes it his chief aim to take her as his bride. In the same way, Christ works to bring His church into the Family of God, judging us worthy to live eternally with Him (Ephesians 5:25-32; Revelation 19:7-9).

Boaz is a type of Christ, the wealthy lord and master of the harvest field, and Ruth symbolizes the Christian being redeemed. His name means "in him is strength," marking him as a man of strong character whom Ruth can trust, and his hometown Bethlehem, "House of Bread," points to plenty and to bread as a symbol of God's Word. Ruth did not stumble onto his field by chance; she was supernaturally led to it. Boaz graciously permits her to glean, and he speaks to her as "my daughter," never mentioning that she is a foreign Moabitess, as though he had already accepted her into the community and perhaps his own family. His speech to her consists of five commands given for her good, not out of tyranny. She must listen and heed his instruction. She must glean only in his field and stay close to his young women, just as Christ tells us not to gather spiritual food from any other source. She must keep her eyes on his field and servants, since he knows the gleaning is not better elsewhere. His young men will not touch her, as the ministry is commanded to tend Christ's sheep in love. She must drink only what the young men draw, representing teaching inspired by God's Spirit through His true servants. In these instructions the Redeemer's concern shows: He keeps His people from harm, nourished, and in the right environment for a successful harvest.
