'Pure' in the Bible

Plans of evil [are] an abomination of Yahweh, but gracious words are pure.

All the ways of a man [are] pure in his own eyes, but Yahweh weighs the spirit.

Who will say "I have made my heart clean; I am pure from my sin"?

Even by his acts, a {young man} will make himself known, whether his acts are pure and upright.

Crooked is the way of a man and a foreigner, but the pure [is] upright [in] his conduct.

[There is] a generation [that is] pure in its own eyes, but from its filthiness it will not be cleansed.
