It's been awhile since I have read Zachariah...WOW! This symbolically rich, Old Testament book instills courage and direction. Even the name, "Zachariah" instills comfort by its meaning, "the Lord has remembered" (Introduction to Zachariah, Amplified Bible).
The Jews have returned to Jerusalem after their seventy year captivity in Babylon. The Lord is reminding the people, "Return to Me" and "I will return to you" (Zechariah 1:3, Amplified).
In Zechariah 2:4, the second angel declares that Jerusalem will be "without walls." But this is not a cause for concern, because the Lord promises that He "will be a wall of fire round about" (Zechariah 2:5).
Use your holy imagination...
There are so many people and livestock that a physical wall can't contain them. Without a wall for protection, I imagine that the Jews might be a little worried.
Would another enemy attack them and carry them off into captivity once again as the Babylonians had done?
The Lord ignites a fire wall around His people! His glory is shining directly from the middle of His people. I imagine His glory as the fuel for the fire wall. The people are protected, safe and secure. God has them, all around. They are living in the midst of Living Flames of Fire! The people respond with courage! Their souls immersed in Peace! They develop confidence in the Lord of Hosts...they have returned to Him, and He has returned to them! Cries of celebration replace the cries of captivity! Songs of joy sung; "He has come into our midst!" It is another day, a different season, a New Beginning!!! The Lord of Hosts assures them that any enemy who touches them is touching His eye! He will not stand for an enemy poking Him in His eye! He swings His hand and the former masters now become plunder for God's people. The enemy is defeated! No more, can he enslave. The people, they are free and their souls are stilled!!!
Amplified Bible (AMP)
Be still, all flesh, before the Lord, for He is aroused and risen from His holy habitation.
I can feel Your Presence, Lord! You are reminding me that Your flaming wall of protection surrounds and Your glory shines from the midst of me. My flesh is still!!!
Thank You, thank You, thank You!!!
