'Pure' in the Bible

The religious service which is pure and stainless in the sight of our God and Father is to visit fatherless children and widowed women in their time of trouble, and to keep one's own self unspotted from the world.

The wisdom from above is first of all pure, then peaceful, courteous, not self-willed, full of compassion and kind actions, free from favouritism and from all insincerity.

Draw near to God, and He will draw near to you. Cleanse your hands, you sinners, and make your hearts pure, you who are half-hearted towards God.
