“for he breaks down gates of bronze and cuts through bars of iron.” Psalm 107:16
Here’s a snippet of the preceding verses, they are referring to God leading Israel out of Egypt from slavery. God is all-powerful and cuts through……well, anything…..the spiritual or the physical.
“He brought them out of darkness and the deepest gloom and broke away their chains. Let them give thanks to the Lord for his unfailing love and his wonderful deeds for men, for he breaks down gates of bronze and cuts through bars of iron.”
