A deep and enduring trust in God serves as the ultimate source of help and protection for the nation. The primary approach among commentators is that a direct cause and effect relationship exists: it is precisely because the people hope and wait for God that they earn His salvation and care [רד״ק, מאירי, חומת אנך]. This collective faith belongs to the entire nation [מאירי] and is firmly rooted in past experience. History has shown the people how God consistently saves those who respect Him and always stands ready to help them [אבן עזרא, מצודת דוד].
This anticipation is not a fleeting wish, but a profound hope that requires lasting patience [מצודת ציון, מלבי״ם]. Even if complete salvation is delayed and the wait stretches on for many days, God continues to function as a helper, allowing the people to survive existential hardships, and as a shield, guarding them against enemies and oppressors [מלבי״ם]. Conceptually, these roles stand in direct contrast to relying on human strength. Trusting in God as a helper replaces the need for a massive army, and relying on Him as a shield takes the place of depending on the power of a mortal king [אבן עזרא].
On a deeper level, especially during times of exile, a distinction emerges between the body and the soul. A person might lack the physical energy or mental clarity to trust God completely and find joy in that security. However, the inner soul recognizes the truth and continues to yearn for Him. It is this quiet, internal hope of the soul that activates divine providence, ensuring that the people are spared from harm and destruction throughout the long years of waiting, even before the final redemption arrives [אלשיך].
