"He shall cover thee with his feathers, and under his wings shalt thou trust: his truth shall be thy shield and buckler."
This phrase makes me think of a magnificent eagle with a tremendous wing span. When they fly, we already know how mighty and strong they are, but when they open their wings, the span looks unreachable.
That's how Our Daddy is! He covers us with a wing span that is unreachable, and we know we can trust in this. He shields us with the truth of His Word, because it is a mighty sword. The shield, upheld by the forearm of God.
