My covenant
The term "covenant" (Hebrew: "berith") is central to the biblical narrative, representing a binding agreement between God and His people. Covenants in the ancient Near East were serious commitments, often involving mutual obligations. God's covenant with Israel, as seen throughout the Old Testament, is a testament to His enduring love and commitment. This covenant is not just a contract but a relational promise, reflecting God's desire for a deep, personal relationship with His people. For Christians, this covenant is ultimately fulfilled in the New Covenant through Jesus Christ, offering salvation and eternal life.

or alter
The word "alter" (Hebrew: "shana") means to change or transform. In this context, it signifies God's immutability—His unchanging nature. Unlike humans, who may change their minds or break promises, God remains constant. This assurance is crucial for believers, as it means that God's promises are reliable and eternal. The historical context of ancient treaties, which could be altered or broken by human parties, contrasts sharply with God's unchanging word, providing a source of comfort and stability for the faithful.

the word
"The word" (Hebrew: "dabar") refers to God's spoken promise or decree. In the biblical context, God's word is powerful and creative, as seen in the Genesis creation narrative where God speaks the world into existence. Theologically, this emphasizes the authority and effectiveness of God's declarations. For believers, God's word is not just informative but transformative, guiding and shaping their lives. The reliability of God's word is a cornerstone of faith, assuring believers that what God has spoken will come to pass.

that has gone out from My lips
This phrase highlights the personal and intentional nature of God's communication. The imagery of words going out from God's lips suggests a deliberate and purposeful act. In the ancient world, spoken words carried significant weight, often more so than written texts. This expression assures believers that God's promises are not casual or accidental but are intentional and will be fulfilled. The personal nature of this communication underscores the relational aspect of God's covenant, inviting believers into a trusting relationship with their Creator.
