Spiritual devotion, no matter how pure it may seem, loses all meaning when paired with moral corruption. After rebuking the people for offering sacrifices without proper intent, the prophetic message shifts to address even the most heartfelt prayers. When a person is deeply stained by sin, reaching out to God is no longer enough.
The physical act of spreading one's hands upward is a universal gesture of pleading and seeking help. The essence of prayer itself is meant to be an outpouring of the soul, a moment of pure thought, a clean heart, and a deep connection to the Creator [מלבי״ם]. Yet, God responds to this display with absolute rejection. He hides His mercy [אבן עזרא, מצודת ציון], refuses to bring salvation, and ignores their cries, even if they shout to Him all day long [רד״ק].
The reason for this harsh dismissal lies in the hands themselves. The very same hands reaching up toward heaven in prayer are covered in human blood, serving as a glaring reminder to God of the person's evil actions [רד״ק, שד״ל]. The primary approach among commentators is that this refers to literal murder and the killing of innocent people. However, another perspective suggests that this is not necessarily about literal murder, as the society at the time was not entirely made up of killers. Instead, it serves as a powerful metaphor for social injustice, extortion, and the cruel abuse of the weak and vulnerable [ביאור שטיינזלץ].
A fundamental principle emerges from this rejection. God deeply desires prayers and sacrifices, but only when they are offered with a complete heart by someone actively working to live an honest life. Evil actions completely ruin any good intentions, as true service to God requires a person to make both their thoughts and their daily actions holy [שד״ל, מלבי״ם].
A unique approach views the spreading of hands not just as prayer, but as a hint to giving charity purely to show off and gain praise, lacking any real sincerity. In this scenario, God hides His eyes, leaving the judgment to angels who only see the outward good deed, but He refuses to hear the accompanying prayer because it is empty of true inner meaning [אהבת יהונתן]. Additionally, the Sages learned a practical law from this imagery. A priest who has taken a human life is permanently disqualified from raising his hands to deliver the Priestly Blessing. Hands that have shed blood can never again be extended to offer a blessing [רד״ק, מלבי״ם].
Through this severe divine anger and the description of such a grave sin, a clear path forward is set. The only way to fix this broken relationship is not by piling on more prayers, but by washing away the dirt, purifying oneself, and completely abandoning the path of evil [שד״ל].
