In the quiet hours of the night, following the exhausting labor of the harvest, a secretive encounter unfolds at the threshing floor. This moment rests on the delicate boundary between fulfilling basic physical needs and deep spiritual intentions, all while maintaining strict purity. After finishing his day's work, Boaz eats a meal, drinks a little wine, and experiences a natural sense of satisfaction [ביאור שטיינזלץ]. However, his consumption is remarkably modest, consisting only of bread and salt, devoid of any physical indulgence [אשכול הכופר]. He drinks in measured amounts, ensuring he does not become intoxicated, thereby preserving his state of holiness [אלשיך, אגרת שמואל].
The profound contentment Boaz feels encompasses several layers. On a level of gratitude, he blesses his food and thanks God for answering his prayers, removing the famine, and showering abundance upon the land of Israel [תורה תמימה, אלשיך, אגרת שמואל, אשכול הכופר]. Emotionally, he uses this quiet time to forgive anyone who might have upset him during the day, ensuring he goes to sleep with a clean and peaceful heart toward all people [אגרת שמואל]. Spiritually, his satisfaction stems from immersing himself in Torah study. Some traditions suggest he partakes of sweet foods at the end of his meal to literally sweeten his tongue for these holy words before sleep [תורה תמימה, אלשיך, אגרת שמואל]. As the leader of the Sanhedrin, he occupies his mind with clarifying complex legal matters, possibly even those concerning the status of Ammonite women [רש"י, צפנת פענח, חומת אנך]. Furthermore, out of a desire for spiritual completeness, he reflects on the necessity of finding a worthy wife in order to serve God perfectly [תורה תמימה, צאינה וראינה, חומת אנך, אלשיך].
When it is time to rest, Boaz chooses to sleep at the edge of the grain heap, seeking a convenient spot to guard his harvest [ביאור שטיינזלץ]. It might seem unusual for the esteemed leader and chief judge of the generation to sleep outside on a threshing floor. Yet, he lives in a time of widespread immorality, where people often use grain to pay for illicit relations. By sleeping there himself, Boaz prevents his workers from stealing and sinning. Righteous individuals distance themselves from theft and take great care to protect their honestly earned wealth [תורה תמימה, צאינה וראינה, אשכול הכופר]. Befitting a man who toils in Torah, he avoids luxury, choosing to sleep directly on the ground without pillows or blankets [אשכול הכופר].
As Boaz rests, Ruth approaches him in absolute secrecy, moving with extraordinary quietness and gentle caution [רש"י, רלב"ג]. Her movements are so silent and imperceptible that they border on the supernatural, almost as if performed by magic [אגרת שמואל]. This delicate operation is guided by close divine providence. Just as Boaz lies down, God casts a deep sleep upon him, amplified by his sheer physical exhaustion from the harvest labor. This divine intervention allows Ruth to uncover his feet and lie down without him noticing a thing until midnight. God's protective guidance ensures that this highly sensitive encounter remains entirely concealed, preventing anyone else at the threshing floor from witnessing it [אלשיך, אגרת שמואל, אשכול הכופר].
