O LORD
The use of "O LORD" in this verse is significant. The term "LORD" in all capital letters is a translation of the Hebrew "YHWH," the sacred and personal name of God revealed to Moses at the burning bush (Exodus 3:14). This name signifies God's eternal existence and His covenant relationship with His people. By invoking this name, David is not only acknowledging God's sovereignty but also His personal and relational nature. It is a reminder of the intimate relationship between God and His people, where they can approach Him with their deepest needs and concerns.

for I am frail
The phrase "for I am frail" captures the human condition of weakness and vulnerability. The Hebrew word used here is "אֻמְלַל" (umlal), which can be translated as weak, languishing, or feeble. David is acutely aware of his limitations and the fragility of human life. This acknowledgment of frailty is a common theme in the Psalms, where the psalmists often contrast human weakness with God's strength and faithfulness. In a historical context, this recognition of human frailty would resonate with the Israelites, who faced numerous challenges and adversities, reminding them of their dependence on God.

heal me
The plea "heal me" is a request for physical, emotional, or spiritual restoration. The Hebrew word "רָפָא" (rapha) means to heal or make whole. In the biblical context, healing is not just about physical recovery but encompasses a holistic restoration of the individual. This request reflects a deep trust in God's power to restore and renew. Throughout Scripture, God is depicted as the ultimate healer, one who can mend broken bodies, hearts, and spirits. This appeal for healing is a testament to the belief in God's ability to bring about complete restoration.

O LORD
The repetition of "O LORD" emphasizes the psalmist's earnestness and the centrality of God in his plea. It serves as a reminder of the personal and covenantal relationship between God and His people. By repeating this invocation, David underscores his reliance on God's character and promises. This repetition also highlights the importance of persistence in prayer, a theme that is echoed throughout the Psalms and the broader biblical narrative.

for my bones are in agony
The expression "for my bones are in agony" conveys intense physical and emotional distress. The Hebrew word for "agony" is "בָּהַל" (bahal), which can mean to be terrified or dismayed. The mention of "bones" signifies the depth of David's suffering, as bones are often used metaphorically in Scripture to represent the core of one's being. This vivid imagery reflects the severity of his condition and his desperate need for God's intervention. Historically, such expressions of deep anguish would resonate with the Israelites, who often faced existential threats and relied on God for deliverance and comfort. This phrase serves as a powerful reminder of the human experience of suffering and the hope for divine relief.
