The Hebrew verb or (אוֹר) means to be or become luminous — to shine, to give light, or to illuminate. It is the verbal root of the noun or (light, H216) and appears in creation, blessing, and divine illumination contexts throughout Scripture.
Light is inseparable from God's character and creative power. The Aaronic blessing invokes God to make His face shine (Numbers 6:25). Isaiah envisions a day when the LORD will be your everlasting light (Isaiah 60:19). Jesus declared Himself the Light of the World (John 8:12), the ultimate fulfillment of every promise embedded in this ancient root.
