Psalms 107:10-16

Some sat in darkness, in utter darkness, prisoners suffering in iron chains, because they rebelled against God’s commands and despised the plans of the Most High. So he subjected them to bitter labour; they stumbled, and there was no-one to help. Then they cried to the LORD in their trouble, and he saved them from their distress. He brought them out of darkness, the utter darkness, and broke away their chains. Let them give thanks to the LORD for his unfailing love and his wonderful deeds for mankind, for he breaks down gates of bronze and cuts through bars of iron.
