God's intervention in the physical world is sudden and overwhelming, breaking into reality with the force of a powerful storm. The imagery of riding and flying captures the sheer speed and power with which Divine providence descends. God is pictured moving swiftly upon a cherub, an angel [מצודת ציון] that forms a part of the heavenly chariot [ביאור שטיינזלץ]. The name of this angelic being shares a root with an Aramaic term for a youth, reflecting its human-like face [מצודת ציון]. The motion is likened to an eagle swooping and gliding through the sky [רש״י, מצודת ציון, מאירי], pointing to a descent of tremendous, unstoppable speed [מלבי״ם]. The fierce blowing of the wind is compared to the beating wings of a bird [מצודת דוד], illustrating that the arrival of the Divine Presence is accompanied by a mighty storm [ביאור שטיינזלץ].
Naturally, this vivid picture is not meant to be taken literally. The act of riding serves as a metaphor to express how a Divine decree comes down to the world in a flash, arriving instantly without any hesitation or delay [אבן עזרא, מצודת דוד].
This imagery also addresses a deeper theological question regarding how God could possibly sit upon anything physical on earth. The Divine Presence does not actually rest upon the physical, crafted angels in the Temple, but rather hovers in the space above them. In this light, moving upon the wind takes on a profound spiritual dimension, referring to the human spirit and the expanding reach of the heavenly angels. God's presence does not attach itself to the clouded, material earth. Instead, He finds His resting place within the spirits of righteous people. Because their souls are rooted in heaven, these individuals serve as the true chariot, bridging the gap between the upper spiritual realms and the physical world below [אלשיך].
