Those words are from "Taps," which is played nightly in the military for signalling "lights out." Those words are from the second stanza. The original version of the lyrics follow:
Fading light dims the sight,
And a star gems the sky, gleaming bright.
From afar drawing nigh -- falls the night.
Day is done, gone the sun,
From the lake, from the hills, from the sky;
All is well, safely rest, God is nigh.
Then good night, peaceful night,
Till the light of the dawn shineth bright;
God is near, do not fear -- friend, good night.
