'Purity' in the Bible

and they see the God of Israel, and under His feet is as the white work of the sapphire, and as the substance of the heavens for purity;

And I turn back My hand upon thee, And I refine as purity thy dross, And I turn aside all thy tin,

my God hath sent His messenger, and hath shut the lions' mouths, and they have not injured me: because that before Him purity hath been found in me; and also before thee, O king, injury I have not done.'

Cast off hath thy calf, O Samaria, Burned hath Mine anger against them, Till when are they not capable of purity?
