News of God's immense power and greatness is destined to spread across the world, eventually reaching the ears of all people. Upon hearing of His mighty acts, individuals from everywhere will be drawn to seek Him, coming to direct their prayers toward the Temple [ביאור שטיינזלץ].
This expression of divine strength involves God extending His arm. Rather than a static display of might, this represents an active, purposeful force, showing how God directs and inclines His power to act within the world [מצודת ציון].
