A song of thanksgiving reaches its emotional peak when it expresses deep appreciation for the leaders and the volunteer spirit that pulsed through the nation. From a place of profound victory, a call of love and recognition goes out to those who stepped forward, directing them to acknowledge the true source of their strength and success. This address is not mere lip service; it is a deeply sincere expression spoken from the very depths of the heart, driven by genuine willingness and affection [רש״י, מצודת דוד, רד״ק].
The primary approach among commentators is that this gratitude is directed toward the nation's great leaders, judges, and officers whose role is to establish local laws. These are the individuals who courageously stood at the head of the camp [מצודת ציון, רד״ק, אברבנאל, ביאור שטיינזלץ], specifically the commanders who led the ten thousand warriors into battle [מלבי״ם]. Alongside this military and political interpretation, another perspective views these figures in a spiritual light, identifying them as the sages, scribes, and outstanding students of Jewish law [רש״י, רלב״ג, אלשיך]. A more unique view suggests these individuals are the nation's historians, the scribes tasked with recording the chronicles and documenting the wars [אברבנאל].
The appreciation then extends to the volunteers among the people, highlighting a dual dedication. On one hand, these are the individuals who willingly offered themselves for battle or worked for the public good [מצודת דוד, ביאור שטיינזלץ]. On the other hand, this refers to the wise teachers who volunteered to instruct the people in Torah and commandments—a vital spiritual task that was impossible to perform under the crushing pressure of the enemy during their years of subjugation [רלב״ג, רד״ק].
Ultimately, both the leaders and the volunteers are called upon to bless God. They are asked to offer thanks for the salvation, particularly because the victory was achieved with a small number of fighters and entirely without natural military effort [מלבי״ם]. For the historians recording these events, this call serves as a reminder to attribute the triumph directly to God rather than to human might [אברבנאל]. Furthermore, the blessing is an acknowledgment of the very privilege to volunteer. Since God is the One who placed the desire and inspiration in their hearts to step forward, they should not claim the credit for their own goodwill [מצודת דוד, אלשיך].
On a deeper philosophical level, a fundamental question arises: How can a person volunteer, dedicate, or give anything of their own, when all the wealth in the world already belongs to God? The answer lies in the act of blessing itself. When a person blesses and thanks God, they effectively acquire their portion in the world, and only then is it considered truly theirs. Therefore, the call for the volunteers to bless God is meant to give spiritual validity to their actions. It ensures that they are giving from what has genuinely become their own through the power of gratitude and blessing [צוארי שלל, אדרת אליהו].
