* **A Universal Obstruction:** The word helps to establish the image of a vail that is **spread** over "all nations." This suggests a comprehensive spiritual condition, a form of blindness or separation, that affects all of humanity.
* **The Object of Divine Action:** The vail that is **spread** is the direct object of God's promised destruction. This places `{{H5259}}` at the center of a prophetic promise where God himself will intervene to remove this worldwide barrier.
* **Symbol of Mourning and Death:** In its context, the removal of the vail that is **spread** is directly linked to God swallowing up death and wiping away tears from all faces [[Isaiah 25:8]]. Therefore, the vail symbolizes the sorrow and mortality that God will ultimately overcome.
