'Denying' in the Bible

Transgressing and denying the Lord,And turning away from our God,Speaking oppression and revolt,Conceiving in and uttering from the heart lying words.

denying justice to a manin the presence of the Most High,

and to speak to the priests assigned to the Temple of the LORD of the Heavenly Armies along with the prophets, asking, "Am I to go about mourning, denying myself throughout the fifth month, as I have these many years?"
