'Pure' in the Bible

So David said to Michal, “It was before the Lord [that I did this], who chose me above your father and all his house, to appoint me as ruler over Israel, the people of the Lord. Therefore I will celebrate [in pure enjoyment] before the Lord.

With the pure thou wilt shew thyself pure; and with the froward thou wilt shew thyself unsavoury.

God—His way is perfect;the word of the Lord is pure.He is a shield to all who take refuge in Him.
