Calling out to God during times of deep distress demands far more than empty physical gestures. It requires a profound honesty where the outward movements of prayer are fueled by true inner purity and the complete consent of the soul. There must be an absolute harmony between thought and deed, the internal and the external. This sincere approach involves lifting the heart out of the mud and the dark depths of sin in which it had been sinking [לחם דמעה]. Alternatively, this elevation is viewed as presenting the heart to God as a precious gift or tribute [אבן עזרא]. To do so properly, a person must serve God with every aspect of their being, channeling both their good and evil inclinations, and even their basic human desires, toward a higher spiritual purpose [לחם דמעה].
The primary approach among commentators is that when a person raises their hands in prayer, their heart must be lifted right alongside them. This creates a perfect alignment between what is spoken and done, and what is thought and intended. It is as if a person reaches into their chest, removes their heart, places it gently upon their open palms, and offers it entirely to God [ביאור שטיינזלץ]. The ultimate goal is absolute transparency, where the purity of the heart is as clear and visible as if it were resting openly on the palm of the hand [לחם דמעה].
However, offering words of confession without actually abandoning the sin itself is entirely ineffective. It is compared to a person immersing in a purifying ritual bath while still tightly holding onto an impure creature; the purification cannot work until the source of impurity is thrown away. Therefore, a person must wash their hands, cast away the filth of their misdeeds, and return to God with a whole heart [רש״י, תורה תמימה]. The hands must be completely clean from theft and violence, and the heart must be free of evil thoughts [לחם דמעה].
This intense level of sincerity is especially crucial because, during times of destruction, God seemingly removes His presence from the earthly realm and retreats to the heavens. Bridging this vast distance requires immense spiritual effort [לחם דמעה]. While angels might accept incomplete prayers or actions lacking full intention, reaching God Himself demands a flawless, pure unity of both the heart and the hands [אלון בכות].
Offering an alternative perspective, some suggest that the physical hands are not the focus at all. Instead, the imagery refers to the clouds of the sky. In this view, the Israelites are asking to place their newly purified hearts upon the clouds, trusting that these heavenly formations will carry their sincere repentance upward, delivering it directly to God in heaven [רש״י, צאינה וראינה, לחם דמעה].
