The grand, rhythmic cycles of the natural world evoke a profound, dual response across the globe: deep awe and joyful song. An enduring sense of awe falls upon the inhabitants of the earth, reaching from the eastern and western edges [שטיינזלץ, מלבי״ם] to the most distant corners of the world [מאירי], all standing in reverence as they face the Temple [אבן עזרא]. This widespread fear and respect stem from the visible wonders and natural phenomena that fill the earth [שטיינזלץ].
Commentators offer various explanations for what these awe-inspiring signs entail. Some view them as the sun, moon, and stars that guide and bring order to the universe [רד״ק, מאירי]. Others suggest they represent the mighty power of rain [אבן עזרא, מלבי״ם] or the sudden, terrifying crashes of thunder and lightning [מצודת דוד]. Beyond physical nature, these signs are also understood as the righteous justice God enacts in the world, serving to teach humanity profound moral lessons [מלבי״ם].
As the day progresses, this initial fear gracefully transitions into joy with the arrival of morning and evening. This shift celebrates the emergence of the celestial bodies as they come forth to illuminate the sky [מצודת דוד], marking the steady transition of time and the beginning of day and night [אבן עזרא בשם ר' משה]. Because these luminaries reliably follow their course without fail, they inspire a global chorus of song [שטיינזלץ, מצודת דוד]. The primary approach among commentators is that this song bursts forth from humanity. People's hearts are stirred to rejoice, pray, and bless God every morning and evening, mirroring the daily prayers that praise Him for creating the light and bringing on the dusk [רש״י, רד״ק, שטיינזלץ]. Alternatively, some suggest that the celestial bodies themselves sing out as God brings them forth [רד״ק]. Ultimately, this song serves as a powerful symbol of great success and the universal joy found in the constant renewal of creation [מאירי].
Alongside this universal, nature-based perspective, there is a distinct historical approach focusing on the Israelites. According to this view, just as the nations of the world were struck with fear by the miracles at the splitting of the Red Sea, they will again experience that same awe of God during the future gathering of the exiles. In this historical context, the daily emergence of morning and evening does not refer to the regular celestial bodies, but rather to God's miraculous guidance. It points to the pillar of cloud by day and the pillar of fire by night, which brought immense joy to the Israelites in the desert and are destined to bring them joy once again in the future [רד״ק].
