'Undefiled' in the Bible

Pure religion and undefiled before God and the Father is this, To visit the fatherless and widows in their affliction, and to keep himself unspotted from the world.

But the wisdom from above is first pure [morally and spiritually undefiled], then peace-loving [courteous, considerate], gentle, reasonable [and willing to listen], full of compassion and good fruits. It is unwavering, without [self-righteous] hypocrisy [and self-serving guile].
