Chaste

"...when they observe your chaste conduct accompanied by fear." (1 Peter 3:2; NKJV)

"Chaste" means pure from every fault, immaculate (Vine’s Expository Dictionary of NT Words).
Strong's defines "chaste" as properly, clean, i.e. (figuratively) innocent, modest, perfect. "Chaste" primarily, has to do with holiness.

"...because it is written, 'Be holy, for I am holy.'" (1 Peter 1:16; NKJV)
