An immense, unbridgeable gap exists between human limitation and God's absolute knowledge. This reality raises a profound question about whether a person is truly capable or worthy of speaking before the Creator or attempting to describe His infinite greatness.
The primary approach among commentators expresses amazement at the very thought that God might require an intermediary. Unlike a human being who relies on others to hear news or gather information, God has no need for a person or an angel to deliver a message to Him. Everything is entirely open and known to Him [רש״י, מצודת דוד, אבן עזרא, ביאור שטיינזלץ, אלשיך]. Alternatively, this idea reflects on the sheer magnitude of God's praise, questioning if it is even possible to count or express all of His mighty acts using limited human speech [רש״י, אלשיך].
As human speech is weighed against divine awareness, one perspective suggests a theme of concealment, asking whether anything a person says could possibly remain hidden from God's sight [מצודת דוד, מצודת ציון, ביאור שטיינזלץ]. Building on this, a philosophical duty arises when someone denies divine providence. If an individual claims their actions are hidden from God, others must not remain silent but are obligated to debate them and prove that God watches over every detail [מלבי״ם]. In stark contrast to the idea of concealment, another interpretation argues that human speech is the exact opposite of hidden; rather, everything a person utters is immediately and fully revealed to God [רש״י].
Another major approach understands this dynamic as a strict warning against arrogance. If an individual presumes they are worthy to argue their case before God and demand a trial, or if they attempt to list all of His praises by adding titles that go far beyond human comprehension, they place themselves in grave danger. Such overstepping risks bringing about their own destruction and removal from the world [רמב״ן, רש״י, אלשיך].
A unique perspective connects this boundary of human speech directly to Moses at the end of his life. While Moses, possessing a supreme and unmatched understanding of the Divine, allowed himself to multiply titles for God shortly before his passing, an ordinary person must not take this as permission to invent their own titles. Since no one else possesses a comparable grasp of God's greatness, attempting to imitate Moses in this way remains strictly beyond the limits of regular human capability [אלשיך].
