'Undefiled' in the Bible

I slept, but my heart was awake. The voice of my beloved! he knocketh: Open to me, my sister, my love, my dove, mine undefiled; For my head is filled with dew, My locks with the drops of the night.

My dove, mine undefiled, is but one; She is the only one of her mother, She is the choice one of her that bore her. The daughters saw her, and they called her blessed; The queens and the concubines, and they praised her.

For such a high priest became us, holy, harmless, undefiled, separated from sinners, and become higher than the heavens:

Let marriage be held every way in honour, and the bed be undefiled; for fornicators and adulterers will God judge.

Pure and undefiled religion before God and the Father is this: to visit orphans and widows in their affliction, to keep oneself unspotted from the world.

to an incorruptible and undefiled and unfading inheritance, reserved in the heavens for you,
