'Undefiled' in the Bible

For this is the kind of high priest we need: holy, innocent, undefiled, separated from sinners, and exalted above the heavens.

Marriage must be respected by all, and the marriage bed kept undefiled, because God will judge immoral people and adulterers.

Pure and undefiled religion before our God and Father is this: to look after orphans and widows in their distress and to keep oneself unstained by the world.
