On one of our trips to Israel several years ago, my wife and I learned that people built walled cities and went out during the day to tend their fields. They returned to their cities for safety at night. At times of war, the city walls also protected them during a siege. If an enemy broke through the walls, the people fled to a strong tower inside the city that they had built as a refuge of last resort. It was powerfully built and stocked with food, water and other emergency supplies.
When we sing, "Your name is a strong and mighty tower," we're saying that God is our protector and savior when all else fails. We can always count on Him.
I hope this word picture will help us sing this song with new and fresh meaning.
