In this Scripture, Zechariah is writing about Jerusalem and the protection God affords to it. But it’s not only protection He gives but security like a wall protecting His people. (Isaiah 26:1) And God’s Presence is also far more than just defensive, His glory (light or fire) is the source of all blessing for His people. (Isaiah 10:17) Together, the city was strong and able to fend off the enemy…just as we can fend off the enemies’ darts today. (Ephesians 6:16)
