Against the temporary and ever-changing nature of the physical world stands God's absolute eternity. The primary approach among commentators is that God is a stable, unchanging reality who exists forever. Beyond simply existing eternally, this enduring nature highlights His absolute truth and exclusivity as the only Master, with no power existing besides Him [רד״ק, אבן עזרא].
A careful look at how God is addressed reveals a shift from speaking to Him directly in the second person to referring to Him in the third person. This transition points to two distinct aspects of the Divine. The direct address represents the revealed aspect of God that a person can approach and speak to, while the third-person reference hints at His higher, completely hidden nature. Ultimately, these two aspects are united, teaching that when the Divine Presence is fully elevated and brought together as one, the exile of the Divine Presence will come to a complete end [אלשיך].
This concept of eternity is further completed by the understanding that God's years will never finish. The concept of ending here is rooted in the idea of completion or conclusion [מצודת ציון], meaning that His existence has no limit, boundary, or final point [אבן עזרא, מצודת דוד]. Drawing from this profound recognition of God's exclusive, endless nature, a deep sense of hope emerges. It is precisely because God outlasts all worldly changes that one can turn to Him, asking that His great kindness bring lasting comfort [מאירי].
