'Unstained' in the Bible

So then I would have the men everywhere pray, lifting to God holy hands which are unstained with anger or strife;

It was fitting for us to have such a High Priest [perfectly adapted to our needs], holy, blameless, unstained [by sin], separated from sinners and exalted higher than the heavens;

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.
