In the dead of night, a young widow sets out on a daring and fateful mission to secure her family's future. She operates with absolute loyalty to the instructions she received, yet she also applies independent judgment, practical wisdom, and pure intentions to shape the entire endeavor.
Naomi had instructed Ruth to wash, anoint herself with oil, put on her festive clothes, and only afterward head down to the threshing floor. However, Ruth alters the sequence of these actions. She first makes her way to the threshing floor and only then carries out her mother-in-law's commands. The primary approach among commentators is that this change stems from Ruth's deep wisdom and her desire to maintain her modesty. Ruth understood that walking through the streets and markets at night, perfumed and dressed in finery, would cause passersby to mistake her for a prostitute. Therefore, she chose to sneak away in secret wearing her regular clothes. She waited until all the workers finished their tasks and went home. Only after safely reaching the threshing floor did she adorn herself and put on her Sabbath clothes, just as Naomi had instructed [רש״י, מלבי״ם, אשכול הכופר]. This behavior highlights Ruth's exceptional wisdom, reflecting the idea that when you give instruction to a wise person, they become even wiser [תורה תמימה].
This nighttime journey was not merely a matter of modesty; it involved real danger. The generation of that time was steeped in immorality, and Ruth greatly feared being harmed by indecent men under the cover of darkness. Consequently, arriving safely at the threshing floor served as a crucial test and proof for her. She viewed her successful journey as clear evidence that Naomi's merit was protecting her and that God was with her. Only after realizing this did she find the confidence to proceed with the rest of the plan regarding Boaz without any fear [אלשיך].
When Ruth finally performs the instructions, she executes them exactly as her mother-in-law commanded [אבן עזרא]. She does not merely go through the motions; rather, she accompanies every single action with a clear declaration that she is doing so solely because her mother-in-law commanded it. By doing this, she hopes that Naomi's merit will assist and protect her [אגרת שמואל, אלשיך].
Ultimately, Ruth's actions at the threshing floor serve as a profound historical correction to her Moabite roots. In the past, Moabite women used seduction and physical closeness to lead men into sin. Ruth performs similar actions—washing, anointing, and dressing up—to draw Boaz's attention, but her intentions are entirely pure and dedicated solely for the sake of heaven [תורה תמימה].
