Evil designs are disgusting to the Lord, but the words of the clean-hearted are pleasing.

All the ways of a man are clean in his own eyes; but the LORD weigheth the spirits.

Who can say, I have made my heart clean, I am pure from my sin?

Blows that wound clean away evil; such beatings cleanse the innermost being.

Twisted is the way of him who is full of crime; but as for him whose heart is clean, his work is upright.

He whose heart is clean is dear to the Lord; for the grace of his lips the king will be his friend.

A false tongue has hate for those who have clean hearts, and a smooth mouth is a cause of falling.
