Helen Berhane spent almost three years in the shipping container prisons of Eritrea. In her book Song of the Nightingale, she shares about the first time she and other women were put in an old metal shipping container that was very hot and filled with fleas and lice:
Pastor Ung Sophal sat in a filthy Cambodian prison badly beaten. His hands and feet were chained for five months. “Only my mouth was unchained,” he said.
“…So I sang to God in prison all the time. Another prisoner heard me singing through a small hole in the wall, so I taught him the song—a bit at a time. He passed it on and soon eight of us were singing.”
Archbishop Dominic Tang spent twenty-two years in prison in China for his faith. He reports:
“Besides my prayer and meditation, every day I sang some hymns in a soft voice: ‘Jesus I live for you, Jesus I die for you, Jesus I belong to you. Whether alive or dead I am for Jesus!’ This hymn was taught to me by a Protestant prisoner who lived in my cell.”
