1 Thessalonians 5:4-8

4But ye, brethren, are not in darkness, that the day should overtake you as a thief:

5for all ye are sons of light and sons of day; we are not of night nor of darkness.

6So then do not let us sleep as the rest do, but let us watch and be sober;

7for they that sleep sleep by night, and they that drink drink by night;

8but we being of [the] day, let us be sober, putting on [the] breastplate of faith and love, and as helmet [the] hope of salvation;
