what was this hymn which now the tenors sang , and what was the answer that came from all the voices so close to me , the words in latin unstrung and only incoherently enveloping me : `` lord , i am come into the valley of death ; lord , i am come to the end of my sorrow ; lord , in thy deliverance i give life to those who would be idle in hell were it not for thy divine plan . ''
