“Oh, God, by your name, save me. … The Lord sustains my life.”

Harrison Odjegba Okene repeated those words as he spent three days trapped under a capsized boat at the bottom of the Atlantic Ocean. A video of the man’s dramatic rescue went viral this week showing his amazing rescue.

A dive team working out of Lagos, Nigeria had been working to salvage a tugboat that capsized and sank. They had already pulled four bodies from the vessel when a diver noticed another hand on his video monitor. When he went to grab it, the hand grabbed him back.

“He was incredibly lucky. He was in an air pocket, but he would have had a limited time (before) … he wouldn’t be able to breathe anymore,” Tony Walker of Dutch company DCN Diving told the Washington Post.

Okene says his life was saved only by divine intervention. He told reporters that he kept repeating a psalm that his wife had sent him via text message earlier in the day.

“I started calling on the name of God,” Okene said. “I started reminiscing on the verses I read before I slept. I read the Bible from Psalms 54 to 92. My wife had sent me the verses to read that night when she called me before I went to bed.”
