'Secret' in the Bible

Hide me from [the] secret plots of evildoers, from [the] unrest of [those who] do iniquity,

In this trouble you called, and I rescued you. Within [the] secret place of thunder I answered you; I tested you at the waters of Meribah. Selah

[One who] lives in the secret place of the Most High will lodge in the shadow of Shaddai.

One who slanders his neighbor in secret, him I will destroy. [One] haughty of eyes and {arrogant} of heart, him I will not endure.
