AELW 11:218
4. He will overshadow you [he will teach you faith] with His pinions [teachers]; and under His wings you will trust [in both testaments you will be nourished through hope.(Luther - His truth will encompass you with a shield.)
5–6. You will not fear the terror of the night nor the arrow that flies by day nor the trouble that stalks in darkness nor the invasion nor the noonday devil.
For all who do not confess Christ or who deny Him are liars, as Ps. 27:12 says: "Iniquity has lied against itself";20 and Ps. 18:44: "Children that are strangers have lied to Me," that is, "They deny Me and My truth, and they do this because they love vanity." And so this lie is truly the pestilence or business that stalks in darkness. If they had only set up their own idea, they would then only be vain and have the arrow flying by day and would put away the truth of Christ undenied; they would not yet be liars, but wavering and careless. But now they deny and contradict and attempt to teach that it is a lie. Therefore they become liars in this very thing. And by this lie they all corrupt themselves. This is truly the basilisk that kills merely by its look.21 For the nighttime fear and the love of vanity and the teaching about it does not yet kill, although it makes people sick. Affirming a lie, however, kills immediately.
