"Abide with Me"

A couple weeks ago, I read the clause "the darkness deepens," and it occurred to me that the repetition involved in the alliteration lends a slight sense of this greater degree.  I remembered that this clause also appears in "Abide with Me" (specifically the second line of the first verse:  "The darkness deepens; Lord, with me abide"), so I thought I would note it here, too.
