'Purity' in the Bible

For our reason for boasting is this: the testimony of our conscience that we conducted ourselves in the world, and especially toward you, in holiness and purity of motive from God, not in merely human wisdom, but by the grace of God.

in purity, in knowledge, in patience, in kindness, in the Holy Spirit, in love without hypocrisy,

But I am afraid lest somehow, as the serpent deceived Eve by his craftiness, your minds may be led astray from the sincerity and the purity of [devotion] to Christ.
